I suppose that kind of command could be implemented on top of the 
current xref API: first, find all identifiers that match this regexp 
(the "apropos" action, or maybe just use the 
identifier-completion-table), then find all references to each of them.

Or probably have a new generic method, do the above in the default 
implementation and allow backends to override it.

Considering we don't currently specify even *one* set of directories 
xref can use (that is one of the goals of this discussion)... How about 
the same way as I'll specify that one, only twice?

Two variables, two generic methods, or so on.
