Unfortunately we're also dealing (in many cases) with pre-existing
software coming over from other OS's. The beancounters want to avoid
rewriting the millions of lines of application code, so they'd rather
add the missing support to the kernel.
If it doesn't go into mainline, we'll just end up with a bunch of
different telco-patches being maintained on the side. I highly doubt
all the applications will get fixed any time soon.
