(Haiku developer here.) Some of those P=high should really be blockers (and the one blocker currently there is a trivial task essentially there as a reminder to do it while making driver ABI changes.) I should do that, actually.
IMHO, Beta 2 should be held back until _at least_ USB Wifi devices are supported. I can't get most of my laptops to work, and the tried-and-true trusted Wifi USB dongles I use on various ARM projects just don't work because Haiku doesn't support _any_ USB Wifi.
I love booting Haiku up in a VM and spending an hour or two here or there pretending I’m one of the lucky few who got a Be Box in the 90s. I was a Super Nintendo and Windows PC clone kid, but I had Neo Geo and Be Box taste.
Just wish Haiku could distributed the old music that came from Be, included such great tubes as "BeOS - it's my OS" and "Virtual(void)" which lamented rebooting multiple times.
