Perhaps user testing reveals that users try to select or interact with
text if it's kept visible, but don't try to use insensitive buttons or
images.

This doesn't really solve the problem; a) people will not consistently
do it b) what if you disable an entire window or notebook page, and
the set_sensitive on the text widget is only implicit. GTK should
default to what's normally considered correct.

So what is an example case where an application-specific change should
be made?

The normal thing should be the default. If you agree, then instead of
gtk_function_to_clean_text(), we should have
gtk_text_set_do_not_clean().

There are always exceptions and weird cases to everything, but we only
try to handle the cases we can think of and consider reasonable - GTK
would be a disaster otherwise. So before adding a setting for this to
GtkText I'd want to hear at least one probably/reasonable use-case
where the app has a good reason to be inconsistent.

Even if there are exceptions, though, the default should be the normal
case, not the exceptional one.
