As I recall, there used to be a way to see what packages in open registry depend on another packages in the registry. For example, one could see a list of what packages that list JuMP.jl in the Project.toml deps. Does this functionality still exists some place?
JuliaHub shows this, for example https://juliahub.com/ui/Packages/JuMP/DmXqY/0.21.6?t=2
That was just what I was looking for, thanks!
