Code review comment for pdbq:pkg-bug-create-with-multi-packages

Thanks Athos, yeah that commit was a bit catch-all of various things at the time I didn't feel worth splitting out more fine-grained, but in the future I'll try to be more attentive to that.

I've rebased this branch on main, resolved a few conflicts, and force pushed.
