But, as far as I understand, the boundary layer has to still be C (the side that loads DLLs and stuff), because of the natural limitations of templated languages and linkers.

And as soon as you change any interface you'd need to recompile more parts of the code. The same can be applied with Rust using dylib. At the end, the glue code always end up being C.

On any given compiler you can make C++ have a stable ABI. You can even do this commonly in practice across compiler versions, even, the standard library typically tries to achieve this.

It's easier to have a long term cross version cross compiler stable C ABI, but if you're talking a single toolchain that simplifies the problem tremendously and you can absolutely do that with C++ in practice at that point
