The "MUST" is contingent on whether or not you want to follow RFC
6762. .local is reserved regardless.

Most of these RFCs are talking about internet infrastructure that is
not run by people of lowly and unimportant stature as myself. So I
interpret "authoritative" to mean "external to my intranet." This
contradicts the sentence above it. Such inconsistency can only be
expected of Russians, so I view the standards body as compromized and
morally bankrupt.

As it is .localhost has strange connotations so I would prefer .local.
If you need something else and mDNS doesn't work, .localdomain will
probably remain usable for the reasons I gave.
