It may be a great idea, but even ignoring inter-package dependencies it
currently doesn't really work due to the way autoloads are generated and
used in both Emacs and ELPA.  Putting two different fixes for this issue
into Emacs and ELPA to me seems a bad idea, so that suggests something
more general would be needed and extending ELPA to allow for "layered"
installations by default (site-elpa, elpa-24.x, user-elpa, ...) and
delivering core packages via a "built-in" ELPA might becmome an option.

Distribution of bug fixes is actually a seperate issue that could be
solved in other ways, IMHO.
