My logic on that is:

If the database is known to be in good shape, i.e not corrupt, after
shutdown during crash recovery, then we should not print the warning at
restart saying "This probably means that some data is corrupted".
There's no reason to believe the database is corrupt if it's a
controlled shutdown, so setting control file state to
DB_SHUTDOWNED_IN_RECOVERY is OK. But if it's not OK for some reason,
then we really shouldn't allow the shut down in the first place until we
hit the end of WAL.

So the option "allow shutdown, but warn at restart that your data is
probably corrupt" does not make sense in any case.
