True enough, some amount of packaging effort would go away with
patchless server support.  Patchless server support doesn't really do
anything to make QA any easier though.

But ultimately, at least currently, a patchless server would have a
significant performance impact.  Most of our customers, as much as they
would like a patchless server, appreciate the performance gains that can
be made for the patched kernel (on what should be a dedicated server

You can probably dig into lkml for that.  Rest assured, we have tried,
more than once in the past from what I understand and were met with and
