Quite the contrary.  To be blunt,  I'm basically saying, if it is in
OSM, then it is fair game to be corrected, aligned and modified.  If
someone is suggesting that data imported into OSM be maintained
pristine, aligned with an external source, then it shouldn't have been
imported to start with.

Again, quite the contrary.  This issue only arises because the import
does align to physical features.   As I said in my previous email,
where the admin boundary is the coastline, and it is the best source
we have for the coastline, then align the coastline to the imported
boundary.  Similarly, when we get a better source for the coastline
than the imported boundary, align the admin boundary to the better
source.

You just don't want to lose your cash..  Put it in a sealed envelope
and get it postmarked.  I'll be back to collect..
