Should work, without wifi of course. You need proper FDT files.

Yes. You build a netbsd.img and install it as kernel.img. It's using
the earmv6hf instruction set.

No.

Wouldn't work for RPI.

Not much of a difference.

?

It's difficult to boot an install image and have no other mass storage to
install to.

No idea.

The documentation wouldn't be NetBSD-specific. Otherwise correct.

You probably need it for RPI3b+.

There is no well defined order. Easiest method to handle this is to
use named wedges, in fstab and in cmdline.txt for booting.

Probably not even relevant for RPI.
