Yes. The fact that the extrude fails (Or is open) would have me immediately go for flat snap. If it completes, I'd pass on the bad geometry. But for the "not a high end modeler, but easy and not cluttered and fun", I could see all these requests I have fall into the "no need" Category.

If you have some idea of your future analysis "extended properties" ui that may handle this, then I can look forward to that.

But I hope you see my point about the fact that it failed being an "information point" for me. It didn't tell me details about "what", but I can make educated decisions from that point.
