You may be surprised! For context, R7RS is the latest standard for Scheme. Actually it's two standards: a 'small' one for the core language (similar to R5RS; this was finished a decade ago), whilst this involves the 'large' standard, which is trying to agree on a "standard library".

Some reasons people may have upvoted this, or otherwise be interested in Scheme:

- R7RS has been dragging on for so long, it may be nice to see some/any sort of status update

- Scheme has so many diverse implementations (Racket, Guile, Gambit, Chicken, Chez, Stalin, etc.) that it's really important to have some common standards.

- Scheme was a major influence on Javascript (along with Self)

- Scheme pioneered many features that are now taken for granted, e.g. first-class functions (it's a "1-lisp"), lexical scope, tail-call elimination, continuation-passing style, call/cc, etc.

- Scheme is commonly used as a scripting language by applications written in other languages (similar to Lua). Indeed, Guile is the "official" extension language of the GNU project (e.g. see Guix, Shepherd, etc.).

- Scheme was/is taught at many schools and university courses

- Well-known textbooks like SICP use Scheme; and indeed guide the reader through writing their own implementation!

- Scheme is used for programming language research (e.g. "towers of interpreters", (delimited) continuations, miniKanren, etc.). Indeed Racket used to be called PLT Scheme (PLT = Programming Language Theory)

that's why i upvoted! this is a pretty significant status update if you're interested in r7rs or scheme in general.
