@rowanc1 I've added an input call (that can be bypassed by defining the MYSTMD_ALLOW_NODENV env var, where the result depends upon the truthiness ({"yes", "true", "1", "y"}) of the lowercased value.

Can you rebase this on the docs PR that just got merged. My understanding is that this will simplify the pip install instructions?

I have lifted the custom build hook into https://github.com/jupyter-book/hatch-deps-selector/, which means that others can also use it.

Simply put, this plugin makes it possible for us to add additional predefined dependencies to our package metadata at build-time by setting an environment variable.

We will update our conda-forge deployment to reflect this.

This PR now should hold until conda-forge/staged-recipes#27417 is merged, so that we can immediately update our feedstock recipe.

@rowanc1 conda-forge now ships the new package required to make this work :)

@rowanc1 this has been tested on Windows and Linux, and works as expected. We can review during today's meeting if helpful.
