Comment:
sure you do have freedom. xbps-src neither is centralized, nor does it dictate anything to you.
it's all open source, so grab the sources and modify+use it to your liking (according to the license), build the packages you want, live happy life.

Some people do have a branch with all their customizations/additions and build packages from that branch.
