Yes, that's close to what I had in mind.
One difference is that I would be inclined to punt more of the
installation logic into the module itself. If "INSTALL MODULE foo"
worked by calling a specially-declared function in foo.so (if
present), it would give the module more flexibility in terms of what
to install based on the version number requested, etc.; some helper
functions could be provided so that the simpler cases require only a
few lines of code.
Modules not implemented as .so files would have a bit less flexibility
thanks to the fact that we don't have any procedural languages
installed by default; how to do versioning for them would require a
bit more thought. (Maybe have a defaultmodule.so to do the work for
them?)
I will consider working on this at some point.
