My experience, such as it is, mirrors yours. Availability of compilers is not a significant problem on GNUish and POSIXish systems. It'd be reasonable to implement "Stefan-style FFI" assuming the presence of a compiler, and then worry about systems lacking compilers later. We wouldn't be any worse off than we are now.
