You misunderstand.  While it probably is also a matter of philosophy,
it's first and foremost a technical issue.  Indeed, implementing
SRFI 0 in Scheme 48 would be technically trivial, but the result would
be useless: in Scheme 48, lots of features exist, but none are
available in the sense of SRFI 0.  Essentially the same holds for PLT
Scheme.
