I appreciate both those efforts very much.

Sure.  Making 'uninstall' workable is one of the reasons I don't like
the idea of "extension" profiles which scribble on "foreign" types:
those kinds of effects are *really* hard to uninstall.  Making the stock
"File" content type addable inside *your* types doesn't cause the
problem;  makeing it *unaddable* anywhere *but* in your types seems a
bit rude, somehow. ;)

I would like for us to find a way to emulate the 'conf.d' model used to
package add-ons for Apache:  the add-ons make all their changes at
install / uninstall time by adding / removing files from that directory,
rather than by scribbling on the main config file.
