> * A script-path spend with the following script (and only that script):
> OP_SWAP OP_DUP <R> OP_EQUALVERIFY OP_SWAP <P> OP_CHECKSIG
Why not this:
<R> OP_SWAP OP_CHECKSPLITSIG
Since `R` is constrained to be fixed anyway, why repeat `R` twice, once in the script and once in the witness stack?
Also, would we want to support non-`SIGHASH_ALL` sighashes?
