Can `pkg prime-origins` be "trained" to pick up flavors?

Hey,

I use `pkg prime-origins` on my servers to pick up the ports that 
Poudriere needs to build for that (cluster of) server(s).

This doesn't work for flavors, or I'm missing a trick.

E.g.: I have installed the "guestagent" flavor of emulators/qemu 
("qemu-guest-agent" in pkg terms), which gets built in Poudriere as 
"emulators/qemu@guestagent".

All good and well.

But `pkg prime-origins` picks it up as "emulators/qemu", which, of 
course, triggers Poudriere to build the whole thing, 
"emulators/qemu@default".

Which I don't need.

So either pkg needs to be amended to be able to recognize and report a 
flavor, or I have to put this in the jail's make.conf on Poudriere.

I'm not sure if there's a place for that in a generic make.conf for all 
ports in that specific jail; you know, one that contains 
all-encompassing lines like

DEFAULT_VERSIONS= php=82 apache=2.4 mysql=80 ssl=openssl python=3.9 
python3=3.9

Anyone?
