This discussion has convinced me not to use landuse=reservoir.
It sounds like the only benefit is its historical use, whereas I've
personally seen benefits of the natural=water approach.
I've mapped quite a number of farm dams as natural=water without being sure
what subtag to use.
I now think
The statement I disagree with is that "We shouldn’t be in a situation where
there is no approved way to map a mapable feature just because the
community doesn’t agree completely on how to map it."
Nobody needs approval to map anything in OSM, so approval only really
matters when there is a

I've been in touch with the person who's mapped a lot of the
waterway=canal+man_made=canal, and they didn't have any specific rationale.
After seeing the proposal page, their preferred tagging is:
Agreed, but just to be clear as it applies to this proposal, in
OpenStreetMap-land, that ship has sailed.
A canal describes "An artificial open flow waterway used to carry useful
water for transportation, waterpower, or irrigation"
I may not fully understand the historic tag, but to me it is unlikely that
every qanat is of historic interest, "of sufficient importance to justify
use of this tag". In some areas, every village has three qanats. It would
be like mapping every fountain as historic.
They're often not
> for me „historic“ does not necessarily imply it is not active.
That's right - what I meant is that we should not treat every qanat as
historic just because it is old.
So we need to map the fact there is a qanat, and then someone with local
knowledge needs to map whether it is
historic=aqueduct is not appropriate.

I just wanted to emphasise that this proposal isn't really about whether to
tag qanats - it's about whether to tag them with man_made=qanat or
There's already 1000 tagged, and they're very patchy geographically. It's
quite likely there's upwards of 100,000

I'm planning to map some qanats, underground channels for conveying
groundwater that have vertical excavation shafts visible from the
surface/aerial imagery (see proposal for example).
This was previously discussed in 2013.
Since then, the role of different waterway tags has been clarified,
