for Debian being somewhat unique in its spread of support.

Having people find the sparc port useful or using it is however not
enough to maintain it. There needs to be a commitment to fix issues and
to respond to inquiries about the current status. However there is
currently *nobody* doing this as demonstrated by the lack of replies to
the release teams concerns (see all the "bits from the release team"
mails on debian-devel-announce@ since the Wheezy release).

Axel Beckert was the only one who stepped up as a porter for sparc, but
he cannot look into the (existing) toolchain and kernel issues[1].

It's the main problem. There are too much kernel issues to use Linux on sparc/sparc64. Last sparc kernel maintainers were leon4 developers and last sparc64 stable kernel was 2.6.32. I have a lot of sparc/sparc64 servers (sun4u _and_ sun4v) and today, no one is stable enough. All servers randomly crash and I have a lot of strange issues with LSI SAS adapters on Txxxx.

We can do best effort to remain sparc/sparc64 alive, but without a real effort to keep kernel usable and stable, there is no solution.

Today, only four T1000 runs on Linux. I think that I will reinstall these servers with xBSD as soon as possible.

This needs to change or it is not realistic for Debian to be able to
keep this port (and I'm not sure sparc64 is in a much better state as a
possible replacement).

P.S. I wondered now if somehow we could attract students taking some
'advanced computer architecture' courses at the universities...

I personally would be more interested in an architecture where one can
actually purchase current hardware (sparc servers on oracle.com seem to
start at ~20k USD). There are quite a lot of those for what I
understand: arm*, mips*, ...
