Hey, how do we generally handle forks of packages that we wish to use on the AUR?

For example, we have package A on the AUR and we have A-fork with a feature that is not merged into A due to various reasons (dead projects, other concerns, etc).

Do we create a new AUR package that is based off that fork? Wouldn’t that pollute the AUR with packages that are similar but are forks of each other?

What if I am developing a package B that depends on the A-fork that is not in the AUR? Do I have to create A-fork as an AUR package so that my package B can be built?
