I was myself considering taking the bit from the Traffic Class field.
This would have two advantages:

Not true, unfortunately. They are all allocated to either ECN
or diffserv. These are both encoded fields, so there are no spare
bits.

You are right.  The bit that I thought was usable (the 6th-most-
significant bit in the DiffServ field) is already used to encode the
sub-group of DiffServ code points.  My mistake; apologies.

So back to Robin's suggestion to take the bit from the flow label...
