Yeah, we'd never want to do that anyway.  You'd never do "2.*.3" to match all
3.y.2 versions.

You don't lookup wildcards.  It's up to the DNS server to resolve
the specific query (1.0.3.updates.sa.org) from the data it has (use
the specific RR if it exists, otherwise fall back to any appropriate
wildcards).

The issue is more of: using /etc/mail/spamassassin to create the channel.cf
file (so SA automatically uses it), versus putting includes in local.cf where
the admin could specify the loading order.  The automatic method requires the
files being named specifically so SA loads them in the right order, which
requires knowledge of channel coupling, which ...  It quickly snowballs into a
large pain.
