Howdy, this is probably a stupid question, as I neither
have DVB-S2 hardware nor have attempted to use anything
but a rather hacked scan from dvb-apps, but...

(implicitly -> explicitly?)

I can see the logic for 8PSK=>DVB-S2, but as far as I
can see, QPSK does not imply purely DVB-S...
NIT result:  12324000 V 29500000   pos  28.2E    FEC 3/4  DVB-S2 QPSK
one of eight such transponders, based on parsing the NIT
tables.  Also, a note from my inital 19E2 scan file to
remind me why it failed:
S 11914500      h       27500   ##      DVB-S2 QPSK (0x05)
May be no longer up-to-date.

Of course, if I'm misunderstanding, or failing to grasp
something obvious if I actually laid my hands on the
code, please feel free to slap me hard and tell me to
shove off.
