Disclosure: I work for Amazon. I’m also the principal engineer for Bottlerocket.
FIPS support continues to be the top customer ask by a wide margin. Unfortunately the timing here is not kind for a new distro with no previous FIPS offering. New FIPS 140-2 certifications are no longer available, and new FIPS 140-3 certifications have to make it through a lengthy queue as the entire industry switches over.
If this were something the dev team could just power through, I assure you it would have happened by now. I apologize for giving the impression that it’s not important. It is, but that doesn’t help the timeline in this case.
