Well, for the current detail that might be true. When all bridges and
tunnels are mapped, all changing surfaces on minor roads, etc. you
will have much more nodes than in this link.

IMHO it is pointless to post a zoom 14 link and say that 19 points are
too much for a linear feature of about 5 km in the link (where nothing
else is mapped to give context). I agree that sometimes linear
features have too many nodes (especially most mappers don't use them
well, they tend to use regular distances regardless of curves or
straight parts) but I hope that if someone creates a tool to simplify
the geometry it will use angles and not just distances in its
algorithm. The current "simplify way"-features are deforming well
mapped ways.

In reality I see mostly the opposite: ways with far too few points (in
low version numbers). In respect to when all these ways will be mapped
with a more appropriate node density (and all the missing roads will
be present, that we are now lacking, e.g. in Asia, Australia, Africa)
deleting some pointless nodes is not a solution (e.g. see here:
http://www.openstreetmap.org/?lat=41.93815&lon=13.70882&zoom=17&layers=M
).

Of course I do delete pointless nodes, but that's far less than I add ;-)
