#s/boot is a bit special but I get your general point. So, let me
rephrase:
the usefulness of #s/foo is determined by the naming convention.

Sure it can:
     % srv tcp!sources.cs.bell-labs.com!9fs test
     % ls /net/tcp
     /net/tcp/0
     /net/tcp/1
     /net/tcp/2
     /net/tcp/clone
     % mount -n /net/tcp/2/data /n/test
     %

Not really, what gets mounted is a Chan to /net/tcp/*/data
as far as I cat tell.

I'm not complaining about /proc/*/ns I'm complaining about ns(1)
which already does some translations of raw data from /proc/*/ns
but not this particular one.
