> the SHA256 hashes would be unambiguously not SHA1 hashes, even when abbreviated Not if your hash happens to not include an 'h'.

  The current SHA-1 representation uses hexadecimal, so only contains 0-9 and a-f.

  Not sure I follow. If the SHA1 hashes use [0-9a-f], and the SHA256 hashes use [h-zA-Z] (or something along those lines), there is never any overlap in characters.
