I'm not in favour of combining ditch and drain. My mind sees a ditch
as a dug-out stream which may flow into a stream or flow into a drain,
the drain being a much larger flow. I see drains as having water flow
several metres wide but a ditch as less than a metre of surface flow.
Those differences can be mapped using the key width.
Other than the width .. what other differences do you see?
To me;
a drain is a ditch that only provides for water removal. Some of these
are small - less that 1 meter wide. The direction of water flow will
tell you if it is a supply or a removal (drain) system.
a ditch could provide water supply or removal and possibly in some cases
either depending on water levels?

Combine "ditch" and "drain" tags into one.

This would require to deprecate "drain" and remove it from the
presets, otherwise we will continue to have 2 tags in the long run.
As far as I know deprecating a tag is only possible if it's usage
declines. Currently its usage increases steadily. How do you intend
to change that? What is the incentive for the mapper to use "ditch"
instead of "drain" from now on? I am not even sure that most mappers
will notice the change on the wiki pages.
