The suggestion is easy, allow a way to specify a set of valid architectures.

I would say "for sure". Info: In Solaris 10 sqlite is used for the
service managenemt framework (SMF). It is possible that the DB is
corrupt in some bad situations. In this case you have to rebuild the
DB (script provided, been there, had to use it).

Put a corruption of /var/db/pkg/xyz-1/+REQUIRED_BY would only affect a
small part, and this part could be even recovered from (pkgdb from
portupgrade is able to do it).

It needs to be automated. Maybe periodic daily... but maybe this is
not often enough after a day of a lot of changes (think about it this
way: do you want to lose a day of changes?). The current FS based DB
is very robust, partly because there is redundant data, pertly because
losing a file just means that the very limited subset of information
is lost (and a reinstall of one port will fix it).
Programming is an unnatural act.
