FWIW `height: calc(100vh - env(foo, 0px));` does work. That's just because `calc(100vh - 0)` is invalid, because `0` in calc get's parsed as a `<number>`, not a `<length>`, and you can't subtract `<length>` and `<number>`s.

That may be something worth special-casing / changing to make work? Not sure.
