One simple solution to the asymmetry is to abolish it. Instead of releasing open source project touted as a "general solution", why not adopt release it as "here is some reference code, it works for my use case. YMMV"
Because that basically would reduce the efficiencies of open source. Rather than having like a single source of Truth for a particular set of functionalities that can improve and iterate over time as a focal point for the demands and needs of all the people who could conceivably use some version of that software, you destroy all that in order to have everybody taking care of their own forks and so obviously you going to be duplicating the work. I mean with unlimited resources it probably doesn't matter but resources are limited.
