The only thing Wingo wrote publicly about this seems to be:

I haven't pushed to see what conditions would need to change to make
JIT support on these architectures desirable for the core developers.
Thoughts, Andy? Ludo?

Yes I am - I saw that.  Thank you for all your hard work on it!

I was recently trying to figure out the issue with the vim-tiny tests
and I broke my ssh access: I failed to realise why setting up a chroot
was so important when you only have access to Sid.  It is quite a bit
of work to get iLO access in my office so I've been putting it off
until I have a couple of days clear to look into it, and I've been
working on replacing the ancient tech needed to speak to early iLO
cards (a java6 browser plugin and old SSL with no hostname

It's not my first debian-ports fun either - I ran a hurd-i386 box for
over a decade without issue.
