gobject-introspection unmaintained?

[Stefan Salewski <mail ssalewski de>]

Is gobject-introspection unmaintained?

I found a github reposity at

https://github.com/GNOME/gobject-introspection

but the issue tracker is disabled.

As you may know, I have done some work on a higher level GTK Nim
wrapper recently. Starting with the API docs
https://developer.gnome.org/gi/1.50/index.html
was a bit hard at first, but then I made indeed some good progress.

But of course the unconfirmed bugs like missing broken bitfield support
may generate trouble?

https://mail.gnome.org/archives/python-hackers-list/2016-September/msg00002.html

Well, bitfields and the other strange points like
g_enum_info_get_method() or g_base_info_iterate_attributes () may be
not a serious problem. But I am asking myself if gobject-introspection 
may work for GTK 4 at all?
