=E2=80=9CAny alternative=E2=80=9D? What about reverting to:
[<public_key>, OP_CHECKSIG]
or perhaps later
[<=E2=80=9Ccompressed=E2=80=9D public_key>, OP_CHECKSIG]
This appears to get away from the issue without introducing a lot of =
other concerns?
(IIRC the RIPEMD thing was justified on convenience and compactness).
Could that be the alternative?
