I think this is the most important part of the question. Because the
possible use case I've described actually doesn't correspond to a
"prod" machine but to a machine that's powered on every 5 years for
some old data recovery. In such a case users just start with an old
system (possibly the one that's still on them if present), and this
doesn't warrant an up-to-date OS.

Moreover, just as I experienced when maintaining 2.4, there's a point
where support for old stuff starts to break again by lack of testing.
And just because of this, users shouldn't always expect to see their
old machines boot fine on a recent kernel. Sometimes there may even be
difficulties setting up a compatible toolchain.

So actually the question shouldn't be "does anyone want such old
machines to still be supported" but "does anyone *need* them to be
supported". And I suspect that for most of them the response is "no",
it's just a convenience.

Just my two cents,
Willy
