Has anyone tried to mark a game private in Steam? Does it work as intended?

I’m not sure to the extent in which they are private, but in my testing they DON’T appear in the following places:

The “Steam Replay” thing.
Whatever ProtonDB uses to query your owned games.
Your recent activity (it also doesn’t also doesn’t count your playtime when displaying the “total time play time” in the last 2 weeks).

Not sure if they are hidden in your owned games list on your profile, but I assume they would be.

Note that the count of games you own (which is public) does seem to include hidden games, if that’s a concern.

I tried this and it properly hid my game, both logged into ProtonDB as well as logged out. Also showed back up when I unmarked it as private.
