Actually, in my experience it's very rare for "modern" GUI applications
to beep.

I agree on the principle to beep in extreme circumstances, but since
these are rare (by definition of "extreme"), we should probably attack
from the other side: use the visible-bell by default, and add a new
function that does an actual beep (additionally to the visual bell) and
then try and find the few places where it's warranted.

That sounds like a bug to me.  In which circumstances does the
visible-bell fail to work?
