There's another school of thought too that says the kernel has no business

yeah, it's an interesting question. But Unix is based on parsing strings.
The kernel already parses lots of strings for paths, for all kinds of
reasons, so adding another element in the kernel that uses paths seems
acceptable.
The bigger problem for Plan 9 that started to bite was i8n. All the Plan 9
messages are English, oops. All the control messages are english. And so
on.
And, further, that network architecture I referenced is much less efficient
than the BSD model -- 5 system calls per accept! so that was starting to
hit us here on the Akaros project, since we imported the entire Plan 9
network stack into akaros, along with the drivers. Linux left us in the
dust on network connections/second. We were going to change it had Akaros
continued.
