Something that boils down to the latter:

o--o--o--o--o--o--o--o--o--o--o--o--o--o  <-Qt
    \                       \
     K--D--E <-4.6-patched   K'--D'--E'   <-4.7-patched
            \                         \
             `-------------------------M  <-latest-stable

Commit M would be generate by

  $ git merge --strategy=theirs 4.7-patched

i.e. M is not a real content merge, but only takes over the contents of
branch 4.7-patched. Someone who had checked out 4.6-patched can just "git
pull" and will be fast-forwarded to M, which is identical (in contents) to

[Except that --strategy=theirs does not exist; it has to be something like

    $ git merge --strategy=ours --no-commit 4.7-patched
    $ rm .git/index
    $ git read-tree 4.7-patched
    $ git commit
    $ git status
    $ git reset --hard && git clean -fd

but only for the maintainer of the branch, of course.]

Anybody can. Y'know this is git. Just make a fork of kde-qt and offer the
branch. I was even thinking about doing that myself after reading the
back-and-forth in this thread. But I'm too far away from hacking KDE these
days. (Yes, I'm just a backseat driver. :-)
