What's the actual use case for nested refs? (Do you have an example page or two where they're useful and there's no way to do it right without nesting the refs?)
“There’s no way”? Well, obviously, there is always a way do it differently… But nested refs can be useful especially with grouped references [1], when a footnote can refer to a source (or, more generally, refs from one group can refer to another group).
Note that there is a workaround for this problem, explained at the enwp help page. [2]
