When Side-by-Side extension on SAP BTP is the right answer I take that path. When standard SAP delivery covers 80% of the requirement I configure instead of building. Clean Core and ABAP RAP and CDS Views keep the SAP core upgrade-safe. You get calm native-English communication and SAP code the next SAP Developer picks up without a handoff document.
