I didn't see anything in the spec[1] about case insensitivity- but as long as the table is being generated programmatically, covering capitalized forms could be in order.

True. The mapping should be in github so people could add all case variations within reason.

I'd personally add (unicorn pivot|Unicorn pivot)--> "Stinking just made BS" on to it.
