The ABI isn't covered by C++ standards, it's target and architecture dependent. For the purposes of this discussion that ABI is stable for C++ vtables on the targets and architectures that VST3 supports.

If a compiler and linker don't follow those ABIs then it would also be close to useless for compiling or linking against shared libraries. So in the wild, all useful compilers do target the same ABIs.

gcc in mingw on windows is the odd duck, but most production software does not support it anyway.

I guess in C++ you are not supposed to link libraries produced by different compilers? Maybe you should use C-compatible interfaces in this case?

You are, you can, and people do. Sure you should use C interfaces, that's what CLAP does, and it's easier to understand as a result.

The C standard similarly does not specify an ABI.
