I was surprised to read this, because I thought the whole purpose of
creating the regional indicators was to allow extension to other
national flags, via those nations' ISO 3166-1 code elements, and to
avoid showing favoritism toward those specific 10 flags.

N3727 says: "The request is to add 26 characters for letters used for
representation of regional indicators, which would be used in sequences
within, for example, emoji protocols to represent the 10 regional
indicators (or possible future extensions)."

TUS 6.2, Section 15.10 does not mention the 10 combinations listed
above, but does suggest they are the only relevant ones: "The regional
indicator symbols in the range U+1F1E6..U+1F1FF can be used in pairs to
represent an ISO 3166 region code... the main purpose of such pairs is
to provide unambiguous roundtrip mappings to certain characters used in
the emoji core sets."

Is it true that the regional indicator mechanism is intended only for
these 10 combinations, in the absence of a formal "future extension"? I
thought emoji in Unicode were no longer meant to be tied to the
repertoires of Japanese telcos.

They're emoji, so I don't think we can really say what they are used
for. The most common use of <1F1EF 1F1F5> might be to decorate tweets on
National Foundation Day.

The presence of both American and British flags does suggest usage
outside of language identification, which I agree maps extremely poorly
to national flags.
