OK. I was informed otherwise when I was working on all the
tmpfs-related code. If this is the case, I will remove all the
Hurd-specific disabling, and it will be enabled shortly. You'll
get a tmpfs /run etc. like everyone else.
Does Hurd support ext3/4 yet?

kFreeBSD supports both linprocfs and linsysfs. If you're going to
integrate well with the rest of the Debian system, the reality is
that this stuff is needed. We shouldn't need Hurd to be
gratuitously different for such basic stuff, it again causes a
large maintenance burden, and means Hurd support will be lacking.

It's not just a case of "working already". I spent several days
writing and testing all that code. From scratch. Just for Hurd. And
this is just one example. We need a dynamic mtab; a static one is
plain broken, and this does have a maintenance burden which Hurd
forces me to undertake. There's special code in every initscript
which mounts something, plus a whole library of shell functions...
which should be deleted at the earliest opportunity.
