If someone is organising a change between two tags that mean exactly the
same thing, where have both been part of OSM for a very long time, and
both are accepted by OSM data consumers as meaning exactly the same
1. I think it's a pointless change. Some on this list may disagree and
think we should "streamline" tags to avoid duplication, but let's
keep that argument to one side for now.
2. No information about what the object is has been lost from the OSM
database (because the tags mean the same thing)
3. No data consumers will be surprised by the change, because they
widely accept both tags as meaning the same thing (but see caveat
below on this).
People might object that:
1. It looks like the object has been mapped more recently than it has been
2. It looks like the "post tagfiddling" tags are more popular with
actual OSM mappers than they actually are
These last two are valid concerns, but aren't as "immediately requiring
of DWG action" as if one of the items in the top list was a problem.
The one that comes closest is (3) - someone (possibly Tomas) earlier
said that they had or were aware of a data consumer that rendered
"moving water" (rivers etc.) fundamentally differently from still water
(e.g. lakes). If that data consumer is "surprised" by "moving water"
becoming "still water", then yes, they will have to do some work.
suggests that "natural=water; water=river" has been documented for 10
has been in use for about as long. For any data consumer to be unaware
of this tag combination for so long seems unlikely, so surely they would
either also be handling "natural=water; water=river" as "moving water"
already, or very, very, stubborn.
