Description

Since 2.0 we've had duplicate keys in our database info blobs for size fields. I was going to remove these as part of the storage engine work but that'd be backwards incompatible. I'm opening this ticket and setting it as blocking for 3.0 so that we remember to remove them when we can make backward incompatible changes.

Also, to be clear, these are duplicates. The same data is available under the sizes key with extremely less ambiguous naming (and will be configurable for storage engines to return whatever they want there).
