What about conditions if a dependency is used on different platforms, python versions, implementations, etc.?

In this CEP I only want to document the current state, mostly as available in the original implementation in conda.

There are a number of extensions in community projects that are out of scope (e.g. I think micromamba has a sel(xxxx): numpy syntax for selectors).

Just a few suggestions (no blockers if you don't agree though) and a question about platform selectors.

Required, `list[str | dict[str, Any]]`.

The simplest form for this section is a list of `str` encoding `MatchSpec`-compatible requirements. These items MUST be processed as conda requirements and submitted to the solver (along with `channels`) to obtain the contents for the resulting conda environment.

Should platform selectors be mentioned here or is that implied with MatchSpec-compatible?

AFAIK, environment.yml doesn't support platform selectors like meta.yaml, doesn't it?

You're right, my bad. Would be a nice feature though.
