IIRC, the current behavior is intentional --- Oleg and Teodor argued
that tsvector values are relatively independent of small changes in
configuration and we should *not* force people to, say, reindex their
tables every time they add or subtract a stopword.  If we had some
measure of whether a TS configuration change was "critical" or not,
it might make sense to restrict critical changes; but I fear that
would be kind of hard to determine.
