No and yes.
It is certainly true that not all SRFIs *are* implemented in all
Schemes. However, most SRFIs *can* be implemented in all R5RS-compatible
Schemes, often trivially. This SRFI (and possibly certain others)
The following two examples illustrate the difference:
If I write code that uses SRFI-1 and then discover that I want or need
to run the code in a Scheme that doesn't implement SRFI-1, I can
simply load Olin's reference implementation.
If I write code that uses SRFI-55 and then discover that I want or
need to run the code in Scheme48, I am hosed.
