> whether it is really "a Scheme" or not
It's not and it's not about being pedantic. Racket changed its name nearly a decade ago and, at that point, it already wasn't Scheme either.
I have a post about where Racket (and Clojure) come from: https://klibert.pl/posts/clojure_and_racket_history.html
You should look at Racket. Racket is a Scheme-like[0] Lisp that aims to be "batteries-included". It includes things like a web-server out-of-the-box.
[0] it is technically a hybrid of R5RS and R6RS, so pedants can argue over whether it is really "a Scheme" or not.
