They're not too big when critical data is in there. Then it's a
matter of what cost to make this wrong decision and have to fix it.

You cannot cross a chasm in two steps. MySQL apps don't generally
lend themselves to incremental improvements because they are so
tightly tied to MySQL's misbehaviors. It would be silly and dangerous
to give people the misapprehension that this transition can be made
painlessly or at low cost.
