My current Intel Mac still has some remnants from running Mac OS X 10.2-10.4 on a G4 equipped Powermac 7300 using XPostFacto. Every so often I run into very odd plists and remnants of long obsolete programs. I’ve used the migration assistant each time I moved from Mac to Mac. All the PPC only apps went away when Rosetta was removed and the 32bit Carbon apps were similarly discarded. Support files sometimes stick around but the transfer agent is generally pretty tidy.
