No need for legacy, optionality, or backwards compatibility. Pebble is not intended as a long-lived system for issuing trusted certificates, it is intended as a test harness.
I think the correct action here should be simply changing Pebble to always produce Subject Key Identifiers which are produced according to RFC 7093, Section 2, Paragraph (3). In other words, they should be the leftmost 160 bits of the SHA512 hash of the subjectPublicKey bit string. This should allow Pebble to do away with all use of SHA1, which still behaving differently from Boulder to ensure flexibility in the ecosystem.

Preserves legacy RFC 5280 SHA-1 subject key identifiers by default and allows callers and binary configuration to explicitly select RFC 7093 SHA-256. This allows the users to run Pebble with
GOFIPS140=v1.0.0.Options idiom was introduced to allow for API backwards compatibility for projects that use Pebble as a library.
