Feature parity between GHC.Stats and eventlog
Both the GHC.Stats and eventlog interfaces expose statistics about a running program.
Some statistics are only available in one interface, eg, #21537 (closed) GHC.Stats lacked a fragmentation statistic that was available in the eventlog.
It would be good that if a statistic is available in one then it is also available in the other. Though it need not be available in the same way. For instance GHC.Stats exposes a number of GCs stat whereas the eventlog exposes this information through having GC events that a user can add up to get the number of GCs.
The aim of this ticket is to track progress towards this goal. If no one objects with the goal, I'll soon look through the two interfaces and see where they diverge, and add a todo list here.
