IDEs like to connect to a repl with a non-tty.

I think, geiser does that, and maybe scheme-mode too (not sure about DrRacket).

In a perfect world, an interpreter should have something like
"channels", and it should be possible to explicitly indicate which
"channel" to read the code from, and which the data.

Relying on a istty() is not a good option, because (read) may even
need to launch a separate GUI frame (window) for input, if the
current-input-port is configured to do so on being read.
