Warn about water=* without natural=water

[mdk]

What steps will reproduce the problem?

1. Draw a closed way with water=pond
2. Validate

What is the expected result?

Validator warning about water=pond without required natural=water.

What happens instead?

No warnings or infos from validator.

Please provide any additional information below. Attach a screenshot if possible.

I currently mapping in an area where I found closed ways with only one tag: water=pond.

According to the wiki, any water=* tag requires natural=water. So we could also offer a fix for adding the missing tag.
​https://wiki.openstreetmap.org/wiki/Key:water also shows that natural=water & water=pond is equal to landuse=pond.
But ​https://wiki.openstreetmap.org/wiki/Tag:landuse%3Dpond says that landuse=pond is deprecated and should be replaced by natura=water & water=pond. Also in this case I would expect a validator warning about deprecated tag value and a fix to replace. But actual the validator only creates an info about an unknown value pond for the key water.
