There are 'approved' tags. These are ones voted on and reach the 
required number of votes, proportion of yes votes and the required 
minimum times for comments on the tagging list and time for voting.
Tags existed before that system .. these normally have the status 
defacto. Tags that have not been 'approved' but have large use might 
have the status 'inuse'.

By seeking the tagging groups discussion a wider world view can be 
obtained rather than a local view possibly of one person.
The voting can be destructive. But the discussions can be helpful.

Agree that landuse=highway makes sense.

I disagree that landuse=highway would confuse a router.. routers look 
for the key highway=* ... not the value *=highway.
So I think the comment that landuse=hightway cannot be used is totally 
wrong.

The acceptance of a tag by renders goes a long way to getting people to 
use it.
Catch 22 is that the renders don't like to use a tag unless it has 
significant use.
One way of encouraging use is to document it well on the OSM wiki.
