I have no problem with incomplete, but I really don't understand the
concept of "sudden end". It sounds like it's an attempt to hide a
rendering decision (what sort of end cap to use) behind a tag that
doesn't quite sound like a rendering tag.

How would I identify a "sudden end" on the ground? How does it look
different to other ends? A road that stops at a brick wall? a cliff
edge?

Personally I like rounded ends and would just make the renderers
render all roads like that...
