The various BSD folks also decided to rather maintain their patches
downstream instead of trying hard to get them included in the upstream
repository... now that we've got a deprecation warning in the configure
script, things fortunately start to change :-)

Likely nobody is maintaining downstream TCI patches ... but we don't
really now for sure - it could be the same situation as with BSD. So we
should give the users a chance to speak up first before we remove it.
