I think the trouble with upgrading the service's vehicle type and frequency is that it is quite a big ask for the service. It would have to generate enough revenue to make all of that justifiable, and the last time GNE proposed to do that (SimpliCity 39), it failed.
In the case of the 39, there was enough vehicles for a proposed frequency increase to happen too, but there never really was for the X21.
