Can you give an example where the BIP itself is not agnostic to 110? I must have missed something!

There are a few things we need to change to comply with the 7 changes in 110:

  • SegWit v2 cannot create a new place for annex data
  • Instead of using OP_SUCCESS, we overload usage the six OP_CHECKSIG* type opcodes to allow for multiple algorithms (proving that this does not introduce other problems is taking some time)
  • Witness bytes for lengthy PQ sigs must be chunked into groups of 256 bytes

It's a challenging problem but not impossible to solve.

Wait you lost me. Are you saying that you want to rewrite 360 back to not just p2mr - i.e. more like it was before the last total rewrite?
