I have use for a method that can remove namespaces similarly to their
addition with addSubspace:, so I hijacked removeSubspace: (which doesn't
seem to be used at all currently), changed its category, and gave it
similar semantics to addSubspace:.
See attached, also at
[hidden email]--2007-nocandy/smalltalk--backstage--2.2--patch-8,
which is against smalltalk--devo--2.2--patch-259.

* kernel/AbstNamespc.st: Make removeSubspace: public, change its
argument to be a symbol rather than a namespace, and don't make it
a subspace of Smalltalk.
