Sure, we could continue to shoehorn features in to 2.x and it will
increasingly get harder, and the bugs will increasingly get harder to
fix. That's where the whole GTK3 discussion started, if you remember.

As long as I maintain the 2.x branch, it will be in maintenance mode
and closed to features. I will gladly give up maintainership of the
2.x branch to you if you promise to port all the features that land
there to 3.x as well.

There's quite a bit of misrepresentation in here ('frozen',
'straightjacket', ...).

Fwiw, a big motivation for all the sealing business was to make it
possible that GTK3 _can_ move faster and incorporate more new stuff
without the need for disruptive ABI breaks. And the GTK3 plans always
included the idea to do more regular ABI breaks, say every 2-3 years
as well.

And yes, I do agree that it is unfortunate that we can't get
everything we wanted into 3.0, but such is life. People have other
priorities, and days only have 24 hours...
