Preparing a glade 3.8 package is trivial. Ubuntu already has one. All
that is needed to install alongside glade 3.10 would be adding
--exec-suffix.

However, if importing it into the archive would be a problem I can just
install it locally or use a preprocessor to load the gtk3 files with
gtk2 once glade 3.10 is working well enough that it makes sense
upgrading to it.

Obviously, gtk2 and gtk3 have some differences to which applications
would need to be adapted. Inability to edit layouts for existing
applications or programming languages that don't have gtk3 bindings yet
is important regression in my view.

Thanks
