I'm not sure the community regularly checks all of the sub-reddits out there or homebrewery for new custom content to include in the community files, but I have not seen a formal request via github. If you want the community to include it in our maintained releases, you'll want to
open a ticket.
Dissecting the community files and checking the wiki out on the github are a great start to figuring out how many races, subraces and class options are scripted out.
