// Use extension1 db for large and medium wikis
'wmgEchoCluster' => array(

We've got a "problem", wikis get bigger. It would seem I upset a few of them earlier this week (not knowing that anything like this depended on the size lists) - https://github.com/wikimedia/operations-mediawiki-config/commit/0ee8c95ab6cd0ad764982881d775a23f3f698b97#diff-32285bf4316ad70244851ab826ae3f07 . Previously it was used as a simple metric whether we run maintenance scripts on them or not.
4 wikis moved from small to medium. Which means they changed from not using the Echo cluster, to using it. Which caused dberrors because the database and/or tables didn't exist. I've fixed that now, but maintaining this list of "exceptions" is somewhat technical debt.
Tables and database are easily created, data isn't migrated so easily. Does it need to be?
What should we doing in these cases?
