Thanks @e-rotteveel_1850 !
This is super-helpful indeed, especially the package that has that metadata.
Do you have an example package that is emitting app_own_environment in the index repo? It looked like it was handled slightly differently in the conda-build code you found, and might be a nested property.. or something. It also seems to be a bool.
It isn't trivial to add fields but also not terribly complicated. I added an item PG-2876 that we hope to get in the Feb 7 maintenance release, but might get pushed back.
Let us know if you're aware of a app_own_environment package as well, that really helps to test this. We likely will not use conda, but simply verify json/index data.
