It's cute, but not easily searchable, unless you want to tag the 3 nodes
with something (which would be a really bad idea); it's had to render
from (unless you want the ellipsis style rendering, and can cope with
rendering all unconnected untagged nodes, and don't care that the size
of ellipsis is dependant on zoom level).

So we have a choice of:

FIXME=incomplete
fixme=Road continues
name=[whatever] (tbc)
towards=[name of place]
complete=no

Personally I think that FIXME should be a free text description, so I'm
not in favour of the first 2 as something to base rendering on.

I really don't like adding semantic stuff to the name tag - what if you
don't collect the name, or the road doesn't have a name? What if there
is a real road out there somewhere that actually has (tbc) in it's name?

I really love the illustrated rendering of towards=, but I might not
know where the road goes, just that it starts here.

I'd vote for complete=no, and rendering it with an arrow on the
unconnected end of the way. Sometimes,  e.g. if you pass under a bridge,
but haven't gone back to pass over it, you may have a way with arrows on
both ends. That is fine. I'd allow and render towards=[name of place],
but that get's confusing in the 2 ended passing under a bridge case.
