Yeah, .dia is good.  I don't know if you can trademark a suffix:)

If we do want to have the suffix indicate whether it's zipped or not, it's
a lot more obvious to put a 'z' or 'gz' in somewhere.  The Dia format is
XML, it just happens to have been zipped by default until recently.
.dia.xml is tautological.  I also prefer having my Dia files zipped, but I
frequently find it confusing that I can't tell from the filename if it's
zipped or not.
