While devassistant is capable of running on without GUI, the Fedora package brings the GUI and GUI's dependencies.

If someone only wants to use the the command and not the GUI, or even if someone wants to install DevAssistant on headless machine, this package brings unneeded GTK3.

Here is the proposal of the split:

Requires:       git
Requires:       polkit
Requires:       python-jinja2
Requires:       python-PyGithub
Requires:       python-setuptools # <- BTW why it depedns on setuptools?
Requires:       PyYAML

%package gui
Requires:       pygobject3
