Hmm, it depends on what you want to achieve, although I think it will be
fair if you require anyone caring about old hardware to keep any relevant
code base, such as drivers, board support, etc. up to date as our internal
interfaces evolve. Otherwise if it works, then I fail to see a reason to
remove it just because you can.

Heh, that machine I raised my objection for is now back in service, after
a failure of its industrial PSU and the installation of a replacement one
(which was a bit of a challenge to track down), serving the maintenance of
the defxx driver for the DEFEA (EISA) variant of the DEC FDDI network

I just need to upgrade it with more DRAM (256MiB supported; not too bad
for an i486) so that it runs a tad more smoothly. An alternative would be
switching to an EISA Alpha machine, however I don't have any at the moment
and chasing one would be a bit of an issue.

FAOD I keep getting contacted about the FDDI stuff as it remains in use
in various industrial and scientific installations and the typical use
case nowadays is getting whatever old gear, which has fallen apart, they
have used to communicate with their equipment over FDDI with a modern
Linux machine, preferably running out of the box with one of the readily
available distributions, and one of those FDDI cards (normally the PCI
variant though), which are reasonably available still.

Sounds fair to me.
