P.S. and let's not forget that Gtk3 really really wants to draw its own titlebars and do its own window management.

Do you mean client-side decorations? https://blogs.gnome.org/mclasen/2014/01/13/client-side-decor...

We're switching to Wayland, where client-side window decorations are required. So this is prepping you for the future.

That must optional, surely. Otherwise it's a dead end.

I believe it's optional on the part of the application developers, but it's not optional on the part of the users. (Although it only happens if you have a compositing window manager, so that's one way to disable it.)
