Hi @RobMulla, these 2 files will need to be updated after the reorg. I'm not sure if you guys have already decided on how you wanna update these:

• 600-new-model.yml
• recommended_models_features.md (multiple lines/links in this file are affected)

Hey @jcyang43 ! Thanks for pulling these paths over.

I’m noticing that this actually fails to build on the docs CI pipeline. Because the base support_matrices/*.csv files were renamed it breaks the Recommended Models & Features page.

I am pulling your branch into my PR #1879 so I can build the new layout scripts on top of your new directory structure, and I'll push the docs fix! Feel free to hold off on merging this until I validate the flow on my end.
