That page is now outdated wrt mips concerns (see below). Do we need to duplicate
the information that we already have on r.d.o/stretch/arch_qualify.html ?

Sure, that's fine.

OK. I have removed the DSA concerns for arm64 from arch_qualify due to this.

AIUI armhf/armel needing local admins should still be a concern, even if mild.
Ideally that wouldn't be necessary. I have updated arch_qualify to reflect that.

I have added you two as armel porters.

We now got more hardware. This is no longer a concern.

There's just one package missing, which is being worked on. See Aurelien's mail.

Once db5.3 is rebuilt, we can enable mips64el in testing.

Not sure about this one... I don't think anybody has stepped up as a porter.

That's sorted out now.
