While we are with this, I have noticed that
flyspell-accept-buffer-local-defs is called from flyspell-large-region, but
not from flyspell-small-region. By the way, since none of both is supposed
to be called directly, might be better to move that call to flyspell-region.
that is the interactive function that will internally call
flyspell-{large,small}-region. Since I would expect this to be affected by
the same problem the preferred fix from those you propose above should also
be applied here.
