Actually, the appropriate place for the final ask is in the bug tracker on gitlab. The devs use the same mechanism to track bugs as they do for features. See this FAQ:
But what this forum area is useful is a sounding board among us users to help develop a feature request from an idea with ad-hock jargon to a proposal with KiCad and/or industry standard jargon.
For example, what I think you are asking is for an IPC (the standard that @Rene_Poschl and his library team strive to follow) calculator interface. (Sorry, Rene, I forget the standard number and version off the top of my head…) Or maybe for one of the other competing standards?
I don’t know the legalities of publishing and freely distributing a footprint calculator based off of a standard that has to be purchased to read… I’m not a lawyer so I’m not even going to pretend to be one.
