Of course it is available. The question is, "Is it already there?" The average blue-haired old lady might be puzzled a bit by a dialog: "You must have gtkmm-2.4-x.rpm installed for Inkscape to work" 'RPM Hell' is becoming a major part of the Download Factor.
But, on sane systems such as debian's apt and RedHat/Fedora's new thingy, and others, you will just install Inkscape and it will take care of the rest. People will not even know, or care, that you use gtkmm.
On Windows it adds to the DLL download weight.
I'm not sure what significance the download size has these
days. By the
way, gtkmm is easily installable on Windows: http://www.gtkmm.org/download.shtml
This is the other major part. Every little bit hurts. If we need it, include it.
Using, or not using, gtkmm is not the sort of major decision that should hinge on a little bit of download size.
And as someone else said in another thread, people are quite used to enormous Windows downloads, because everyone has to ship all of MFC, CommonDialogs, yadda yadda in every application installer.
