I am sure there is a reason and I believe it has
something to do with the fact that GTK3 is a recent
addition. Things might change in the future.

I don't see why not. It should work on any system
that has Python3 installed, at least that is my
understanding. I'm sure someone will correct me
if I'm wrong.
OTOH if you want in insure 100% portability with any
script, you can use pyinstaller.
To install for Python2:
pip install pyinstaller
For Python3:
pip3 install pyinstaller
