I don't know what exactly characterizes your notions of "base

I understood that R6RS would be organized into a base language and a set
of library modules. So, to me, the base language is what you have if you
do not import any library modules.
If "base language" means "what's needed to
build the other stuff," then that would clearly mean that the flonums
need to be in it.

If you mean "library" means something that an
implementation may or may not support, then see the rationale of the
SRFI why that wouldn't be a good idea.

Whether bits of the library are optional is another matter. I can see
arguments both for and against it.
If you think that SRFI 77
should really be made available in R6RS as a set of library modules
rather than just one big blob for organizational reasons, then I fully
agree with you---we just didn't have the methodology to do it when we
wrote the draft. I'm hoping we might have it once we get to putting
stuff into R6RS.
Yes. My biggest dislike of SRFI-77 is more to do with exposing these
routines in the base language rather than pushing them off into the library.
