better-defaults is an old project which has been there for at least a 
decade in some form (and has a fair amount of stars on its archived 
repository on github: https://github.com/technomancy/better-defaults). 
It's the original "emacs starter kit".

So yes, it must be widely used.

Something like that, with a blinking or some brief "busy" animation.

A moving reddish shape should bring enough attention, but of course 
different users have different levels of sensitivity (as the discussion 
in bug#47574 has shown). Only a practical experiment can tell.
