Making large numbers of points all at once will almost certainly result

It's annoying to add things to the database and find them not appearing
on a general map - is there not an 'all data map' ? Sidewalks - which
The map is the data, not the rendering. You do see a more complete
rendering in show map data mode or in an editor, but that, inevitably
means you can show less attributes, if you want to keep the clutter down.
I've used to mark kerbs as they should be marked. This leads to why I
left OSM years ago:
That sounds more like a plan than a map. Having a reasonably high level
of abstraction is actually useful for most of the applications of the
map. I don't know how OS handle it, but I assume they have both the
abstract mapping details to support 1:10000 and up, and a higher level
of detail for the sort of plans used in planning applications, rather
than dynamically deriving the abstracted roads from the detailed kerb lines.
In fact, when people do micro-map things like footways (still as lines),
the transition between those areas and more abstractly mapped areas
tends to be awkward, and it tends to imply barriers that don't exist in
the real world. We currently have very poor coverage of more useful
things, like house numbers, and in many parts of the world, even road
names, so the map is not going to grow well if you insist on everyone
micro-mapping to this level, so most of the map is always going to
abstract sidewalks into the road.
It is possible to map roads and pavements as areas, but you loose
direction information when you do that. Again, transitions are awkward.
Also, the surveying tools available to amateurs make mapping detailed
kerb lines almost impossible. At best they will be relative to a
carriageway centre which has an uncertainty which is often wider than
the road.
