Well it all depends on what one might consider to be "cruft"!

I've never actually tested 4.15, but for me 4.13 is still the only
stable version of Xen I can run on some hardware.  4.18 is unusable on
this hardware, as is 4.20, and thus by association 4.15 is also suspect....

I should test 4.15 I suppose -- but I have a bunch of patches I would
need to make to the pkgsrc module workable in order to test it properly,
and so that's been on the back burner, especially for summer.  Such a
test might narrow down the range of changes where the problems first
crop up for my hardware.

(I have been running 4.18 already for quite some time on hardware where
it is stable.)

I've got a stack of patches for Xen itself (as of 4.20) that fix a lot
of the porting nightmares for BSDs and which might help clean up the
pgkrsc modules quite a lot -- stuff that probably should have been fixed
a decade ago, but I haven't been able to work on upstreaming them yet.
Overall my fixes should also make it easier to have multiple versions of
Xen installed at the same time, both for testing and for safer upgrade
paths.

Anyway I don't mean to say pkgsrc should keep 4.15 (or 4.13!) around --
I can keep those modules around for my own needs.  I just wanted to
point out that there are ongoing problems with more recent Xen versions,
and for my own purposes a crufty old version that doesn't have those
problems is worth keeping in my own systems for now.
