🗒️ Summary of this message: A pull request for deprecating midstate and hash1 in Bitcoin's code has been made to simplify the internal reference miner and remove dependencies on cryptopp.
📝 Original message:Yes, that's possible and what
https://github.com/bitcoin/bitcoin/pull/535 does. However, deprecating
midstate (and hash1) would allow for much cleaner code.

A pull request for marking midstate (and hash1) as deprecated can be
found at https://github.com/bitcoin/bitcoin/pull/538
