[Tagging] natural=wood status=approved?

[Warin]

Hi,
  The wiki page for natural=wood has the status shown as 'approved'.
http://wiki.openstreetmap.org/wiki/Tag:natural%3Dwood

This was set to 'approved' on 20th May 2010.

I have gone back through the tagging list archives (starts October 2009) 
and seen no discussion on natural=wood, cannot find a proposal for it...

So would the status be better set as 'inuse' to reflect that it has not 
been 'approved'?

What should be the practice for similar status issues?
