TaskScheduler histograms are taking advantage of suffixes to break stats into different processes/pools/task types but it's becoming hard to reason about the config ( issue 807616 ).

It would be very nice if we could just define which histograms are basis and which one stack on top of which base without having to explicitly list all variants of that base. Listing all variants is not only tedious, it becomes error-prone and hard to read when multiple suffixes stack.

How about something like

<affected-histogram-suffix name="MySuffix"/>

which just generates all the variants of this suffix recursively applied on top of the variants of MySuffix?
