I think I tried to answer the question to my best knowledge before:
The location you’re searching for is yet to be created. The location @cfausto suggests would be the natural location where it might be located in the future.
We need to get some questions solved together now about how we want to continue with this. I must confess that my motivation suffered a bit recently about us not advancing in answering some design questions in the first place. My very personal attempt was obviously to create some very zynthian suitable patches, and others opted more towards assembling a set of upstream pulled “pure original” soundfonts.
Meanwhile I did create some unified patches from some VSCO/VCSL patches. I think we at least need to find answers to where to create the library and how to submit to it.
