How can i tell why every fork was created? How can I tell it'll fix my issue? The idea of maintaining a fork for the sake of a patch affecting only one version

How can i tell why every fork was created? How can I tell it'll fix my issue? The idea of maintaining a fork for the sake of a patch affecting only one version of the original software is silly. Not only that, others mentioned "networks" but how do users tell what I patched, diff every fork one by one? Perhaps there is a feature I don't know about since PRs just work for me.
