Yeah, once you start using tricks to get what you want, you lose
flexibility.

No, I cannot. Recent tests don't seem to be showing any black splotches.
Maybe 3.7's radiosity has been fixed somewhat after all. It used to
happen when I rendered meshes with high-count radiosity. Strange black
patches would appear, and higher count values only made it worse. If I
run into it again, I'll post the relevant code.

Yes, that is what I'm doing. If you're having a hard time getting rid of
radiosity's artifacts, the method can save the day. The render times
generally tend to be a bit higher, and you'll always see some of the
surface normal. Overall, the result is on par with many other types of
radiosity you see out there. You know, the ones with visual noise :)
