I'm not sure this is *so* critical. There message means that TM
won't be in Mars by default, and that they don't plan new
development on the project.
The removal of TM from Mars doesn't prevent us from consuming it in
our TP. We actually don't even use the Mars repo to get TM
currently, but already their dedicated repo.
The fact that there won't be new development is not important as
long as they welcome patches.
So the project is not "killed" in a way that it's not usable any
more, it's only that not much will happen from its current
contributors.
