Then he would have the reverse problem: once he installs a user-local hg 
extension, the bundled (official) hg extensions wouldn't be reachable 
anymore.

The answer here comes into two possibilities, both of which have to do 
with Mercurial and none with Python itself:

1) Mercurial could make hgext a namespace package (see Peter Otten's 
answer above)

2) third-party extensions for Mercurial should never install into the 
"hgext" package but rather in a separate top-level package or module 
(presumable called "hgsomething")
