This is sad to see, but I understand this decision.
Because one time I was trying to build one software for Windows, using MinGW. It was
written using C++ and Qt5, as Fedora Media Writer are. And it was hell. So, I just dropped
and forgot about it. Another guy with Windows as primary system did it instead of me.
P.S. Then this feature proposal was first introduced, and I have seen news article on
phoronix with wireframe images, I thought it was rewritten for GNOME (GTK3, glib2, and
etc).
