Ofcourse if the label will also be used to classify traffic for

If this is the case, and I hope it is...wouldn't is simply make more
sense for the SP to ignore the FL all together? Therefore, if the FL
were pertinent on the other end...
The diffserv use case would use an e2e flow label to allow all diffserv
classifiers along the path to correctly reclassify the packet, even if
the protocol and port numbers are obscured by encryption. That only works
if the flow label value is preserved right up to the last router on the
last LAN on the path.
