Yes, but even that pulls a number of other rnrs modules.  It seems to me
that SRFI-9, even if it’s slightly more verbose, would be much less of a
burden here.

I agree in general, yes.  But when the run-time footprint can be reduced
at little cost, it seems nice to do it.

Exactly: the problem I have with R6RS is that it basically re-implements
several SRFIs or APIs otherwise available in Guile, sometimes just for
dubious aesthetic reasons–e.g., SRFI-1, SRFI-9, SRFI-3[45].
Traditionally ice-9 modules have not used them.

(Note that R7RS is likely to make that even worse...)
