When you go from a PSBT to a raw tranaction then you lose a ton of data: information about the previosu UTXOs needed for signing, BIP32 derivation paths, EC signatures...

I doubt we'll ever *get rid of* the raw transaction API, for backward compatibility and testing purposes. But I expect that users in multi-party transactions (where the ability to analyze...

Also, in practice a single function is often harder to use - if you want to hash a series of things it's nice to just throw them all into a...
