Mind you MCP alt alert is set 1000AGL or at FAF alt if IMC and we would never want to see use of V/S down low. Our AB guys do same thing too.
Many ways to skin a cat, our Boeing procedures were MCP altitude set to GA altitude passing the FAF on a VOR approach/GS capture on an ILS...if MCP ALT was set to 1000' AAL then ALT CAP would occur if using VS when not locked on to a GS..Airbus had the advantage of FPA which lessened the workload and allowed for more precise flight path control
