Anyway, I asked about this because because the use of global variable 
(flymake-list-only-diagnostics) seems like it would make supporting 
multiple projects at the same time more difficult.

If global diagnostics are only reported to a particular buffer, perhaps 
we could do without the global variable by tying refreshes to a 
callback. That would require an extra hook, however -- like 
flymake-global-diagnostic-functions.
