Yeah, agreed. I get the impression it's a small team. But there is a long-tail of weird x86 features that are implemented, that give them amazing compatibility, that I regret not mentioning: * 32-bit support for Wine * full x87 emulation * full SSE2 support (generally converting to efficient NEON equivalents) for performance on SIMD code I consider all of these "compatibility", but that last one in particular should have been in the post, since that's very important to the performance of optimised SIMD routines (plenty of emulators also do SIMD->SIMD, but others just translate SIMD->scalar or SIMD->helper-runtime-call).
