Hi George,
This is interesting proposal, indeed it looks fair, given XenServer and
SUSE basically have this option already. In practice, I'm not sure how
useful that would be for Qubes OS, given we don't consider DoS-only bugs
security issues needing coordinated disclosure. It feels like infoleak
or privesc bugs are either found earlier or affect newer versions too
and in both cases they fall into standard security support anyway. But
that very well might be just an impression due to no such policy
earlier.
In any case, in Qubes OS we support Xen 4.17 and 4.14 - the latter only
for about 6 months more.
