Have you tested this and does it actually work?
I can hardly imagine that, because in

+     if (frontendType == SYS_DVBT2 || frontendType == SYS_DVBS2) {
+        // DVB-T2/DVB-S2
          SETCMD(DTV_STREAM_ID, dtp.PlpId());

"frontendType" will never be SYS_DVBS2 because in line 816 this is
already limited to SYS_DVBT or SYS_DVBT2:

   else if (frontendType == SYS_DVBT || frontendType == SYS_DVBT2) {

I would assume that this also requires some additional code in VDR's nit.c
in order to store the "PlpId" in the transponder parameters of DVB-S2
transponders (see case case SI::T2DeliverySystemDescriptorTag).
