Yes, they definitely said they heard the "3.0 job design" arguments but are happy with the 5.0 design and wanted to continue it in Endwalker.

Realistically, I don't think the design could ever be 3.0 again, because 4.0 is when we got job gauges and had some of the worst clunkyness removed. But they don't want to do 4.0 design either.
