You would also be repeating work from various other groups who are doing
things in either COPRs or the Fedora XFCE mailing list. Kevin Fenzi
(irc:nirik) and Adam Miller (maxamillion) are doing a lot of this work in
their spare time. Helping them out would move the following issues a lot.

1) A lot of plugins that were in 4.10 and earlier are no longer in 4.12
2) A lot of 4.12 was actually built around a gtk3 and tools which aren't in
EL-7.

Both of these are actually going to take a lot of work with upstream and
the software itself to

a) make new plugins which work with the 4.12 framework
b) work on patches or newer upstream releases to make it work with EL-7.

Once those are done there looks to be plans to get 4.12 in EL-7. I am
hoping to get some time to look at scl's for EL-5 and EL-6 and those would
be ones which might do fine with a refresh.
