It depends on how intermingled the changes are. If the applications are siloed, you can go fast.

If they depend on or update each other, it needs more than simple automated testing.

A developer makes a simple change that works for itself, but some other application that has not been changed, gets broken. Or worse 2 developers make changes that go in opposite directions.

That said, having long cycles that leave trivial updates waiting for months is not acceptable.
