Does Racket blindly inherit from Scheme because of history?
No, Racketeers choose what to take over and what to leave behind.
Why are multiple values useful?
Multiple values enable a smooth functional style where pedestrian programmers
may have to use clumsy package-unpackage or, worse, im

it would be awesome to have this, and of course keyword arguments, as
first-class constructs in Racket.

I am not sure how much usable values/call-with-values are in Scheme.

You're referring to 1994, "An efficient implementation of multiple return
values in Scheme" ?

Racket has more forms right?
