It is very unfortunate that we conflate the two conditions.

We can't even reconstruct the override by looking at whether
_SITE_METHOD == local, because even local packages may be overriden...

feedback on the rest of this eries, I don;t want to invest too much time
if there is no chance of it getting in...
