I don't know how my scenario reflects the main benefit of no-code... the visual designer "code" was so complicated that literally nobody could work on it. We were all trained to make changes -- both the business users and a small group of developers. In theory they could make changes but in practice it was just too complex. Some minor things were changeable by them but the big changes started to pile up.

When we converted to regular code, the business users loved it because all the changes that were too complex to do in that product suddenly became both possible and quick. They lost the ability to make small changes themselves but, given that we could do it almost instantly for them, they didn't care. We're all better off because nobody has to know the quirks of this priority system anymore or be limited by it.
