My mantra is, and I'm sure this sums up the attitude of many people here:
Topology, Topography, Presentation.
In order of importance. So a clean database is very important to most of us.
I say most because you are right in saying that there is no overarching
authority or standard here. People just tend to self-organise when it comes
to how people represent features in the database. It works surprisingly well
