As it has been said before I think, there is no need for a cul-de-sac tag.
A cul-de-sac is obvious either because the end of the way is a
cul-de-sac or because other tags make it one.
At which end of the way would be a cul-de-sac if some tag were on a way
to indicated it?
Or, maybe, we're inventing ways with a cul-de-sacs at both ends?

It's not a question of understanding what contributors do, it's a
question of the contributors understanding what the wiki says, clearly:
"This tag is mainly useful where a road or path ends close to another
way but where it isn't possible to get through due to a barrier or other
obstruction which may otherwise look like a mistake for a connection to
the nearby road. It helps other mappers and quality-check programs to
understand the situation correctly."
What many contributors do is indicating obvious cul-de-sacs like saying
the tip of my finger is the end of it.
Or should we complain that all cul-de-sacs are not tagged?  There are a
great many !!!

Others make the mistake tagging a cul-de-sac traffic sign with noexit.
On one hand, this is obviously trying to tag the cul-de-sac where it is not.
On the other hand, such signs exist because the driver can't see the
blocked end of the road. That does not happen when one looks at a map.
That's another error that was spotted by a lynx-eyed contributor and
that I corrected in another part of the wiki.
