very surprising to see this SRFI, in that, it's unclear to me how usable multiple values as a concept were up to this point in r6rs without the existence of (what seems to me) a corner stone syntax like define-values.

Somewhat offtangently, on reddit someone brought up a quite useful potential operational distinction between multiple values and list wrapping https://www.reddit.com/r/scheme/comments/zdp1b5/srfi_244_multiplevalue_definitions/iz50062/  , but this is actually unspecified. Maybe it should be specified somehow somewhere, to make multiple values a more appealing feature? Although maybe not necessarily by this SRFI.
