There should be a setting to disable telegraphs for tankbusters, stack markers, aoe markers, floor telegraphs and a lot of other things.

Then there will be that time you forget the fight in a party finder instance, cause a wipe and get kicked because you stood in the bad stuff. (I'm assuming you are serious with that line.)

Doubt it. People manage that with telegraphs without getting kicked.
