"Should"?  Why?  What's wrong with having many namespaces?  Separate
namespaces have many good properties - for example, a chrooted program
can still manipulate AF_INET sockets normally.  (This can be looked
upon as good or bad, depending on your inclination.)

Personally, the main reason I want ps -M ... -N ... instead of a
separate crash-type program is that I can be sure it's the same ps,
supporting all the same options in exactly the same way, with all the
same output formats, etc, etc.

It occurs to me that it might well be sufficient to have a tool that
presents a kernfs-style mountable interface, but instead of being
driven off a live kernel it's driven off netbsd.0.core and netbsd.0
files.  It seems this might end up being more work than the other way,
but it seems to me it should be at least considered.
