It is certainly worth seeing what coverage a weak pointer would have as
a matter of correctness, which would be a matter of going through all
the cases where gtkmm increments the reference count when wrapping a
GTK+ getter function, and therefore acquiring an ownership which GTK+
does not of itself intend to pass, and establishing whether it matters.

Weak pointers can be useful apart from that, of course.  Most tool kits
have something of that kind, but some are more thread safe than others.
