In the latter scheme, the fork would be the listing-worthy repository. I might merge the improvements with my repository, but I must avoid responsibility to merge improvements.
It’s bad enough having responsibility for some fonts. What I seek for my fonts is that others should make the improvements people request of me. For instance, I make the comma accent double as the cedilla. I do not do this because I think it is the best approach, but because I seek to minimize my work. Disability means can’t do the work! Someone else please steal my fonts and make them better. Maybe it will happen. And the same with package build scripts.
