A validator MUST support {SHA-1, SHA-256}.
A signer MUST support {SHA-1, SHA-26}. A signer SHOULD use {SHA-256} for
its higher security strength. However a signer MAY use {SHA-1}, such as for
compatibility with an installed base, lower computational cost, or easier
implementation effort.
Consensus?
Yes, with a note that if the IESG tells us they want something other
than SHA-256, that's fine.
