There is a strong counter-argument though, based on the increase of online meetings and screen sharing scenarios...
Not everybody always remembers to silence screen notifications while sharing screens.
Which leads to more-than-once-a-week situations of "Hi - full question or comment notification that probably shouldn't be seen by co-worker/boss/client" popping up during the share.
A simple "hello" --wait for answer-- protocol makes it a quick way of checking if it's a good time.
