Yes, there is a case, in my package [Grassmann.jl](https://github.com/chakravala/Grassmann.jl) there is the `*` product for a geometric product and I intend to use `★` for the Hodge star dual operation. These are two entirely separate operations both within the same package.

Whether it’s on the list or not is not that important to me, but I don’t see any reason against it.
