It means that this could be noted in a new field, or as " (M)" or " (H)"
etc. at the end of the description, or verbose as " (historic)", or even
in a comment - but normally we reserve comments for any info that's not
a part of the source.

One hopes.

Yes.

We also didn't mention that new fields might be introduced later.

For the purpose mentioned by Peter - determine if "foo" is the subtag
for language "bar", where "ancient" helps to decide that it's not -
the "ancient" info is relevant, not how it appears in a "bar" record.

For the purpose mentioned by Addison - determine if subtag "foo" is
a macrolanguage - it's the info "macrolanguage", not how it appears.
Checking if subtag "foo" is the target of an extlang-prefix is not
exactly straight forward (but an algorithmic solution).

And for the purpose mentioned by me - check if "foo" is a pure 639-3
subtag - we have no proposal based alone on the LSR.
