Just a comment, OpenStreetMap allows anyone to map anywhere. Just because
HOT doesn't have a task for it doesn't mean you are unable to map.
I personally have a concern that we are to quick to add a task, if we
didn't add any tasks from tomorrow I think we have enough unmapped or
unvalidated tiles in the system to keep everyone currently mapping occupied
for the next year or two.
That doesn't mean we shouldn't add any new tasks but it does mean we ought
to get better at adding tasks that we can finish rather than leave 25% done
for two years or more.
