Do they have custom map support yet? Most of my time in TF2 was not spent on official maps. It seems like server browsers have been disappearing since the jump from MW1 to MW2, where the quality of the PC experience is dampened for the sake of making it more like the console experience.

Nope. Custom game modes and all that exist solely on existing maps or the testing plane/box maps.

The cloest Overwatch has ever gotten to a custom map was when a (offical) OW map designer was desinging a level with his viewers on Twitch one day. Blizzard than later suprised everyone by putting it in the game for a limited time.
