I cannot speak for AlmaLinux, but it's incorrect to say they're not compatible. They are most definitely still compatible with the upstream distributions. Yes, they have made some changes that make them quite different from the upstreams, but this was their choice and it works for their community and their overall goals. I personally don't see any issues with what they've chosen to do, but that's my extremely narrow view as all clients I work for only use RHEL or Ubuntu.
In regards to STIG, this makes me think of the "scap-security-guide" package that helps the openscap package run tests for compliance like PCI-DSS and HIPPA (among other things). While it is true that we mark ourselves as a "derivative" of RHEL in that package, it doesn't mean we have any certifications or the like and we certainly do not claim to have such certifications. The only thing we actually have officially is a CIS benchmark set at cisecurity.org.
AlmaLinux on the other hand appears to be upstreaming themselves into the content itself, which I think is pretty cool (https://github.com/ComplianceAsCode/content/tree/master/prod...). I've always wanted to see Rocky Linux do the same thing for the past few years, but I don't know what it would take. I've asked our security team some weeks back to look into what has to be done, so maybe something will happen. I just know it will take a long, long time to get things figured out either way. (As much as I'd like to look into it myself and work with the security team, I just don't have the time in between my personal life, day job, and the project.)
