Note that I said "try to avoid" and "unless it's absolutely necessary". 
I can certainly imagine cases where it is necessary, and I used it
myself a few times too.

But with regards to your example:  I have a non-editable Gtk::Entry in
one of my apps as well and don't see the problem you described.  The
entry is a preview area and its text changes quite often.  Neither does
it shrink when the text is short, nor does it expand when the text
doesn't fit into the entry.

This could be a fix in GTK+ 2.0, but actually I've never seen the
behaviour you described.
