Changing the default namespace inside of an extension means breaking the
extension on nearly every single wiki it is installed in.
So yes, it's easier for a site administrator to move namespaces around
than it is to change the default for an extension.
Also, I'd recommend that any extension that defines custom namespaces to
provide a way for site administrators to offset what namespaces are used.

Brion has already marked 100-199 for site administrators.

And I'd like to point out that every one of the extensions currently
listed inside that area provides config to use different namespace
numbers. So you should have no conflict worries.
