Offering that option to the admin sounds like a good thing, since
(as Alvaro points out) the build of the replacement index could take
considerable time but be done without the lock.  Then the swap
done in the first quiet period (but without further admin action),
and the drop started.

One size doesn't fit all.  It doesn't need to be the only method.
