You can do that now, just put the libs and abstractions in the same folder as the patches.

Pd looks in the local path of the patch as well as the system & user specified locations, plus you can use [declare] as well:

Well I don't know about how extended worked, since I really never used it. I only mean to 'export' into a pd distrib that is only intended to use with a particular patch that only has the requirements of that patch
 
if you could do that, then you could just autogenerate pd-extended, no?
