allow natural=bay on lines

However, there are almost 400 bays mapped as linear ways, especially in areas with fjords such as Norway, Greenland and Chile. Many of these bays are long, narrow and curving, so it is reasonable that some mappers like to map these as linear ways.

Wiki was changed in https://wiki.openstreetmap.org/w/index.php?title=Tag:natural%3Dbay&diff=1727691&oldid=1696854 on 21 December 2018 (and I agree with that change)

Equivalent JOSM issue: https://josm.openstreetmap.de/ticket/17727 (implemented)

This is ok, but it means bays mapped as areas will now get area=yes.

[matkoniecz]

What about existing natural=bay mapped as areas without area=yes? Will it cause problems?

Maybe for workaround for iD design here it would be OK to have two entries - natural=bay as line and natural=bay as an area?

It will probably cause problems for someone (as any change in the geometry rules will), but not for iD.
