For the record, either way, it doesn't matter.  As far as I'm concerned, 
if someone finds a nasty hack that is there for an obsolete target, 
eliminating it is still an obvious fix.

There is a corollary, if someone finds nasty target/host dependant code 
then one way of fixing it is to obsolete that system :-)  Suggestions 
for host/target combinations welcome (ChrisF, sorry *-pe has already 
been nominated :-)
