While that isn't a bad idea, it seems to me that it's adding mechanism
to get around a problem that we don't need to have in the first place.
The only reason this risk exists is that the patch changes a monolithic
postmaster option (-D) into two independent options (-D/-X) that in
reality should never be independent.
Essentially, you're proposing Kevlar shoes as a solution for the problem
that you want to walk around carrying a loaded gun aimed at your foot.
The shoes might be a good idea anyway, but the primary problem is
elsewhere...
