To give an example of why qualifiers should be sparingly used, taken to the extreme, every artist, character and copyright tag on this site should be given a qualifier in order to drive the chances for collisions and ambiguity down to zero, however that would be ungainly and IMO would look terrible.
I believe they should be used only when absolutely necessary. The simpler a tag is, the better. It wouldn't hurt to add the qualifier, true... but then again, it wouldn't help that much either.
If all of a sudden, we get a ton of posts from an artist/copyright/character/chemical named aldehyde, then it's easy enough to add a qualifier at that time.
Why not make it from the beginning so a maybe unlikely but still good possible scenario isn't even created.
My guess is when the artist's name is a real word you'd find in every dictionary, then a qualifier is needed. . That's far away from taking it to an extreme :3.
And I believe that we might have an Aldehyde here around with formol (which isn't exactly an Aldehyde, but still somewhat related) (post #1347257 maybe?)
