I'm sorry, but this is FUD. Those changes were not about annoying users and
developers but they happened because the design wasn't complete yet. The
GNOME developers emphasized that several times. You cannot blame them if
third party developers start using internal or unfinished APIs.
Moreover, they have actually finished the design recently and it's now
considered stable, see .

"for me", "for some of us", "I don't care about Wayland support". Do you see
a pattern here? I mean, I don't think I need to explain more why those are
actually very bad arguments.
Linux desperately needs Wayland to replace X11 because the latter is an absolute
mess  and a security nightmare. They are still finding and fixing X.Org
security issues all the time and the fact that the X server runs as root
is a huge problem.

You know that this basically doubles the amount of work that the maintainers
have, don't you? I think you underestimate the effort required to fulfill
your request. Making both MATE GTK2 and GTK3 builds would mean the MATE
maintainers would have to maintain approximately 100 packages instead
of just 51 as of now . Do you really expect the maintainers to take
this additional load of work just because some users are feeling they
don't want to use a GTK3-based version of MATE?
This isn't even taken then security implications into considerations
into account which arise when having to deal with effectively a
second desktop which builds on top of an outdated and soon to be
deprecated version of GTK.
Like with Qt3, we can be quite confident that Debian is going to
drop support for GTK2 at some point simply because having a set
of libraries which are used by so many other packages in the
distribution without active maintenance and thus security support
is not acceptable in Debian.

Sorry, but we cannot take request of individual users into consideration and
as I have explained above, there are actual reasons why this particular
decision was made, the primary concern being security. We are not
going to rollback any decisions which improve security in the long
If you feel uncomfortable with the changes, you are free to stay on
Jessie which is going to be supported until 2020 or switch to any
other distribution of your choice. I am pretty sure that most
distributions will drop GTK2 support at some point, so you will not
have much choice, I'm afraid.
Alternatively, you can try building MATE based on GTK2 yourself,
or, use a source-based distribution like Gentoo which will allow
you to build MATE with GTK2 support without much effort.
