Goodluck getting Valve to respond to this or do anything at all. I've reported multiple ways of changing various settings in TF2 that can be used as exploits over the years and the vast majority of which haven't been patched in anyway.
BTW there's a few other ways of editing the Spy Cloak volume along with a shit ton of other sounds. There's a specific one that I reported to Valve over a year ago at this point and again a few months later that hasn't been addressed and works in sv_pure 1 and sv_pure 2 by default. Though sv_pure 1 can be configured to block it and a ton of other ones including the one posted about and explained in this thread, just a massive pain in the ass to confirm whether or not a server is setup correctly for scrims/league matches.
Was about to mention how one of the top teams in open has 2 players on it that actively used some of the spydecloak scripts enough to get banned in UGC&RGL, but fortunately that team died.

SpaceGhostsCoffeeComanglia made a video on this recently, it's more than just hearing spies. You quiet/louden any game sound you want, so you can make footsteps, decloaks, and the uber crackling noise really loud and everything else quiet. It's really really dumb

Technically speaking the one mentioned in this thread and how to do it, isn't the same. Yes you can replace the sounds but you can't actually keep the stock one and make it louder with the one in the OP. The one I posted is FAR worse.
The short of it is that you can change the volume of every sound file in the game
Things to mention specifically though just to hammer in how game breaking this can be.
- Medics getting and Holding uber/kritz +
- Medics using uber/kritz +
- Uber fading/kritz +
- Footsteps +
- Spy Cloaking/Decloaking individually at that you can keep stock volume for cloaking and louder decloaks +
- Sentry Gun beeps +
- All class voice lines
- Ambient Sounds +
- Sticky Bomb "arming" that little beep sound stickies make when ready to detonate
- Sticky Bomb colliding/sticking to a surface +
- All Weapon Sounds individually to basically every weapon (some reuse sounds) and even down to the actual firing or just reloading or vice versa
- Ammo/Health respawning +
- Ammo/Health pickup +
- Explosions I'd imagine most people would make this quieter +
+ = I fully confirmed this can work with this file edit. The rest I didn't bother trying because I could already do 99% of the other things I tried.
I can continue for a shit ton of other super low-key things that actually could be really important (see Ammo/Health respawn and pickup currently it's so rarely heard it's unimportant), to the super obviously important (ex. decloaks, guaranteed uber knowledge, stickybomb placement, etc.
Oh, and one final last tidd bit about it. You can change the volume by such a low-key amount it would be difficult for anyone to confirm you're actually doing so even if you stream, so long as you have some low-music in the background. The Volume change can be as little as +1% or -1% possibly less or as much as +/-100% to +/-1000% depending on the file.
Edit1
Please continue to report this to Valve. Especially if you rarely send them feedback.
@Valve: If for some reason one of you actually reads this, pls check you feedback email link. I'm assuming my email address is included since it's a required field. Just look for "Comanglia" in there you'll find my gmail address. If you have issues finding a report referencing this I'm not hard to find.

For those curious, I'd rather have Valve reach out to me at this point because I'm leaning heavily towards feedback that includes my email is either blocked/filtered, or at least that's what I hope is going on.
Edit2
Someone ping me in 30 days, I'll explain to everyone exactly what file it is, where to put it, how to add/change volume of basically every sound in the game.
Oh and Fun Fact. This file is blocked by the pure settings in CSGO.
