Are you actually intending to edit the code in the cloned version of the package? Or are you just trying to have two different versions of `A` as dependencies for two different versions of Julia?

If the latter, don’t `develop A`; instead `Pkg.add` the version that you want to pin for the older Julia version.

Note also that you can always download a new version of `A` to anywhere you want using any method you want. If you then `develop(path/toA)` you will use that version of `A` in that particular environment. `develop` just means: put an entry into `Package.toml` that points to a local folder. Whatever code sits there will be used in that environment. That could be your own code or a package that you downloaded (by whatever method) from anywhere else.
