Well a meta repo isn't a mono repo. In that situation you can still update individual repos. Analogous to running a DB operatioj without a transaction. But that said, no I don't think you need a meta repo. You need something. Call it a Change set. MVP would be say merge commits in 4 repos. If any fail then revert. If they all succeed then deploy in a specified order.
