IDL compilers are a very unusual special case. First, they do not abstract. They merely provide a language-neutral way to specify an interface that must exist anyway. Second, a decently written IDL compiler can emit safe but highly optimized code that a human cannot maintain.
 
That is: where IDL compilers are used, the abstraction/modularity boundary already exists, and the question is solely a matter of what language should be used to describe the interface.

Yes. Certainly.

The problem with C++ is that IMHO the abstractions are very poor: they
obscure a lot without really hiding much complexity...

So why are you in favor of IDL compilers? To me that is also an abstraction that is a compromise. You could simply use a library with helper functions, and know what is going on, instead of design a whole system around compiler-generated communication idioms.
