[...]  However in practice one can also assume that any field longer
than 13 characters results in a locked account.

(This would then require custom checks to be added for systems such
as FreeBSD which don't use the standard Unix DES 64-bit password
encryption, but that's not so hard to do.  [...])

It's not hard to do for any individual system.  It's a nightmare to try
to maintain such checks in a master source tree.  I know of three (I
think) free Unices and one commercial one that break the "length!=13 ->
invalid" assumption, and as CPU speed increases make the old DES-based
hashes less and less secure in practice, there will be more.
