R5RS and earlier don't have libraries.  The things I listed as lacking
in RnRS (whether 6 or 7) are taking into account all optional libraries
listed in the respective standard.  E.g. the "libraries" document of the
R6RS has nothing for networking or threading, and the standard libraries
of R7RS-small don't have anything for hash tables.

That's a different thing entirely.  A library written *specifically* for
Guile might use low-level facilities found in a specific Guile version.
This has little to do with the viability of writing Scheme code that runs
on various Scheme implementation.

(One should also note that the transition from Guile 2 to 3 is not like
the Guile 1.8 to 2.0 transition at all.)
