I guess I’m out of the loop. I thought R7RS has been around for a while now. What is the process discussion about?
R7RS small was ratified in 2013, but work on R7RS large is ongoing. This work seems to largely involve adding SRFIs to the large language standard, which has evolved over a series of “editions”.
Ongoing discussion on R7RS-large is happening here nowadays: https://codeberg.org/scheme/r7rs/issues
I recall that in the early days, the Scheme standard was controlled by a large group of notable researchers, and a unanimous vote was required to add a new feature. That process collapsed when R7RS-large was proposed. Now it looks like the work is being continued by John Cowan and 3 other people (looking at the codeberg link from @Drakonis), using the SRFI process to generate and test proposals (each SRFI is implemented by multiple Scheme implementations before it gets added to the standard).
