I am not too sure how useful that is if it just replaces the SOA from
the zone - I think it would be more useful if it would use either the
SOA from the zone or the generated one (whichever is greater - and use
YYYYMMDD00 for the generated one).

Yes, but unless I have misunderstood the other options, it's currently
the only useful one (at least for me).

BTW, maybe a lua hook would be possible (for maximum flexibility)?
