It's more a case that it's not done because it's not implemented.  __*
rules could, for the most part, be evaluated when they are first needed
in meta rule evaluation and then cached.    

IIRC the author of rspamd cites this as the main reason why it's
faster than SpamAssassin. I don't know the details, but I gather it
also does some kind of reordering to minimise the evaluation of
expensive rules.
