The sunset period of SHA-1 is approaching [1] and FIPS 140 certificates
have a validity of 5 years. Any distros starting FIPS certification for
their kernels now would therefore most likely end up on the NIST
Cryptographic Module Validation Program "historical" list before their
certification expires.

While SHA-1 is technically still allowed until Dec. 31, 2030, it is
heavily discouraged by NIST and it makes sense to set .fips_allowed to
0 now for any crypto algorithms that reference it in order to avoid any
costly surprises down the line.
