Good =/= interested to cross-breed...
Hell, you can have a white dragon who pillages nordic villages, takes the women hostage, polymorphs into a humanoid and rapes them, leading to the births of white half-dragon children.
(Ok, a little intense, but still...)
I think that it goes more into the matter of whether true dragons are close to "lesser" societies or not. Lycanthropes, for instance, are a common breed of monsters, as unfrequent as they can be. However, over time, their offsprings become less and less like their ancestors and becomes lesser versions of them, like the skinwalkers.
A human woman who has been impregnated by a trumpet archon could give birth to either an aasimar or a half-celestial human, just like an aasimar can be a descendant of half-celestial parents. The geniekins (ifrits, oreads, sylphs, undines and sulis) seem to be commonplace because of certain regions where genies are commonplace.
However, if true dragons aren't interested by how humanoids live their common lives, half-dragons might be unheard of. If a half-dragon is known, then his or her draconic parent isn't obscure either. If a village pays tribute to a dragon for protection (be by force [evil] or by equal exchange [good]), don't be surprise to see a half-dragon roaming the streets.
Still, a draconic race could be a recent discovery. Hey, if they can make shadow-touched characters to be revelant as with the fetchlings (no seriously, the Plane of Shadow isn't a common reference in Golarion), pretty sure a draconic race wouldn't be as jarring as people think.
In the end though, the half-dragon template has tired the community by a huge margin. Would people even BE interested to see a race based on the half-dragon template? (That's how I see the aasimar and tiefling now, just sayin') Paizo is a business afterall, they have to go for books that will generate a profit.
