Well that's a bit of a balancing act, isn't it? "Why isn't this feature on the site, it would be more useful to me; also, that feature is annoying and useless to me" - says literally everyone.

Thus, we get a built-in editor (less friction, yay/too rudimentary, boo) and popups (OSM events, yay/Popups are now everywhere, boo). And endless discussions on "this should be more/less prominent."

I don't think there's any official edict, but the approach "I don't like this and I'll make my own version" is at the very least workable (as opposed to, say, Google Maps).
