Review comment:
I know splittable meta is not implemented by this one but I think we should
prepare for it? Not adding new difficulty, by introducing more 'there is only
one meta region' assumptions...
And I do not think we need to disable a table before altering it. The issue
here is named 'Altering meta', not 'disabling meta', so let's try remove the
disable/enable stuff and just implement the alter?
