Since the actual packages aren't really being deleted when superseded, one 
could just save the pacman .db files to get the set of up-to-date packages at 
that time. I can't say if the old packages will stay up indefinitely.

AFAIK there's no reason why you couldn't bootstrap an older toolchain using a 
newer toolchain. But this is not my area of expertise.
