No.  SRFI-0 includes some blurb about module systems with restricted
scoping rules etc, but leaves everything to some possible future
module system SRFI.

But maybe we could wait for SRFI-22 (Running Scheme Scripts on Unix)
to finalize, which defines some additional names for script
interpreters, such as scm-r5rs or scm-i3e-1178-90 or scm-srfi-0, which
would support the language implied by the name.  Though personally I
dislike this because of possible name clashes if more than one SRFI-22
Schemes are installed.

A possibility would be to add a command line option to Guile,
something like this:

guile --use-srfi=1
guile --use-srfi=1,6,17

which would load the corresponding SRFI module after booting and add
the corresponding `feature identifier' to the list in `cond-expand'.
I think this would be the cleanest solution.
