I was looking at payment channels in mimblewimble and I wasnt clear if they
could be bi-directional, by revoking transactions. The whitepaper talks
about increase value v.

I think a transaction in a channel could just be revoked by B signing a new
return transaction, but at a lower height than the transaction being
revoked. New transactions that A signs would be at a decreasing height.

Publishing spends would have to be timed carefully, and the size of the
channel would gradually shorten, but they have to close anyway...
