I'm reviewing the constants file for other missing constants. Looks like TEXTAREA is also missing. This is just manual inspection though... I should write a script that can automate checks like this... 🤔

In https://github.com/ExactTarget/fuelux what we did was use call the CommonJS or global version and see if would error out just placing them on the page. We could probably cycle through all the exports of index and place them on a page in production mode and see if they run, but required props would be needed.

Another option would be manually add deprecated component paths (that have moved) to a list.
