This would be a supplement to the normal Edit Counter.

We definitely cannot run the full Edit Counter on every wiki. But some queries like the month/year counts (and even the timecard) are actually quite fast, so might be able to loop through the user's active wikis and collect the results.

The idea here is that instead of breaking down the counts by namespace, we'd break them down by wiki. It could look ugly if they have a ton of active wikis, but I think it's worth exploring.

First step here is to run some tests on stewards or the like, users who are active on a lot of wikis, to get an idea of how slow this would actually be. Then we can decide which queries we'd want to include. Note that the "General statistics", specifically various log counts, are by far the slowest to query for from my tests.

We could include relevant global log counts, specifically for stewards (number of global locks, etc.). That should go reasonably fast.
