Yeah, all the compilers will have different implementations and ABI and it'd be unrealistic expectation for them to be completely compatible. Instead, IIRC the current approach is to have a compatible format for specific common tasks. There has been some effort in SG15 to ensure consistency/interoperability across module implementations which led to https://wg21.link/P1688R0 https://wg21.link/P1688R0. This was mainly due to difficulty of scanning dependencies for build systems so there needs to be a standardized format to consume module information. One caveat: this group has been inactive for a while due to the pandemic, unfortunately.
