Or, and I mention this mostly for completeness as it'd be a really hard sell: persuade Debian that the Pi is such a big deal we should move the armhf base CPU optimisation back down to v6+vfp2, no thumb. That would still work on v7+vfp3 hardware, but with some speed penalty. > You could probably reuse the armhf name (and ld.so path), This was the sense in which I meant it's not a new port. It would be a new repo.
