[Talk-GB] featdesc & featcode

[SK53]

Hi Dave,

The wood/forest and water ones I've seen are entirely useless in OSM as the
relevant natural tags represent exactly the same information.

For some external sources imported to OSM retaining the original codes is
useful when there is not a precise 1:1 correspondence to tags, but that is
not the case here.

Not only can they be removed safely, but there may be merit in adding them
to the tags automatically deleted when something is edited (such as the
editor tag). There are one or two rareish codes in the data according to
taginfo which I dont recognise (
https://taginfo.openstreetmap.org.uk/search?q=FEATCODE).

Regards,

Jerry
