"Category aliases" might be a general approach to solve problems like the current with gendered category names. There might already be some ideas or discussions out there around that.
[x] find related tasks or discussions around the technical aspects of category aliases
[x] think of ways how this could be implemented and utilized for gendered category names
[x] prototype a solution ( maybe as an extension )
[] Where should category redirects not behave like a top level category and how could we do that?
[] What side effects could be happening? Example: A redirect category is turned into a real category. What happens to all the pages inside?
[]Could we use #alias or so to not surprise people with unexpected redirect behavior?
