When vote is accepted by the game (Restart/End/Qualify), it can give some time to insim program to cancel that.

We already have similar behaviour with IS_JRR (join request response). That allowed us to filter joins instead of spectating a player if something is not fit.

That's the same case with my request. I send the TINY_VTC (vote cancel) right after I get the IS_VTN (vote notify), but timer still appears, which can bother people around.

I like this!

That's indeed useful. It's annoying when you see the chat spammed either when you as a user hit the vote and THEN it gets cancelled, or when people indeed "catch up" and restart, but after that you want to cancel it once again.
