Is the formatting done with some kind of auto formatter?

Yes! It was done by nixfmt under default settings, which is the "official" nix formatter AFAIK.

Yes! It was done by nixfmt under default settings, which is the "official" nix formatter AFAIK.

In this case, please codify the formatter in the file. I as far as I know that works fine for devshells.

PS: I started updating the toolchain file some time ago, but ran into build issues (and therefore never uploaded it). I'll try and dig out the branch to see if everything I ran into additionally has been resolved.

Do you think that could happen in a follow-up?

Done. Not sure how useful being able to do nix fmt is considering that command tries doing very dumb things like recursing down gitignored folders (tho apparently that just got deprecated a couple weeks ago) hunting for nix files but perhaps it's useful to communicate what formatter we're expecting.
