That wasn't meant in that way. There might be several implementations
providing similar functionality. But there are certain "basic"
facilities, where, when provided in too many ways, portability
actually suffers. Consider the effort wasted when porting a large
C library (like GTK+) to a single FFI SRFI - while neglecting all
implementations that support a different FFI SRFI.

Indeed. That's what I'm saying.

I did never suggest such a thing. This SRFI is a special case.
It is (in it's current form) simply too ambitious, while providing
too little abstraction and portability.
