The problem with protecting stock and allowing people to ban all unlocks is that for most classes the stock primary is the best choice, but poor little Pyro can have what is almost universally the default choice for comp pyros banned under these rules.

Same goes with Secondaries - a Sniper without Jarate is nerfed, but it doesn't affect his ability to hit heads; a Soldier without Gunboats is greatly reduced in his capability of doing his primary job in HL - bombing in and getting picks.

Basically what I'm saying is you either need to have everything up for banning (impractical) or protect some of the weapons the community can identify as 'essential'.

A pretty cool way to keep track of some stats would be in the form of another badge - a 'Competitive' badge that would track games won through this matchmaking system and rank up accordingly, similar to how the Dueling badges work.

If there's one thing that people love in TF2 it's getting shinier items, and if you can only get a Gold Competitive Badge through a system like this I suspect you'd encourage people to keep playing.

Donated with a request for a Huey Lewis signed Degreaser, happy to supply the item/gift wrap myself for the worthy cause if needed.
