Relations are visible* if the editor makes them visible.* The iD editor introduced an entirely synthetic primitive: the "area". Thus, in iD, the "area" is visible. The iD editor, or an editor like it, could introduce a "grouping", and make it visible. Relations are not only possible to visualize, they're interesting, Click on Main Street and see the 12 bus lines that use Main street? Interesting. Click on a line and learn it forms the USA/Canadian Border, 8,891 km long, consisting of 5000 odd line segments? Interesting and instructive. A series of iD plugins for visualizing specific types of relations would rock. And of course in iD style they'd be called something different, like, say, "Turn Restrictions" or a "Public Transit Route" or "Site" or a "Level 8 Administrative Boundary between X and Y". The word relation need never come into it. ------------------------------------------------------------------------------ By all-but-ignoring relation editing, Potlach and iD only make it easy to ignore or even *damage* relations. It's all downside. That's not what you want for entry level editing. A good experience for a starting user is they made a positive contribution, they saw the results rendered, and they did not mess anything up. When the editor makes messing up an invisible single click (or inadvertent click) operation, it leads to stress all around. Relations are invisible only in editors that* leave them in the shadows.* An editor that ignores or tries to hide a thing is unlikely to be the best way to edit (or preserve) the invisible thing. It's a form of "fake simplicity": making a given edit seem to be simpler than it really can be.
