They don't have to be, we just use that as the default.  We have a
variable to turn that off and use our own tooltips.

I presume GTK users would prefer the GTK tooltips, though, because
they preserve the look-and-feel of the other GTK applications, and can
be customized in the same ways.

You propose to switch to "tooltips" that pop up in a special buffer?
