Review comment:
I hit all of the existing places you mentioned @rdblue. I'm going to
resolve this conversation.
I chose not to refactor the current scan classes that extend `BaseScanClass`
to use `StaticScanClass` in hopes of making this PR more digestible.
I can do that in a follow up if needed be.
But this now passes the unit test for the refined error message for every
metadata table.
Feel free to open this conversation back up if you have any concerns. 👍
