Er, no - that way madness lies.  We get enough rubbish in OSM from 
"substandard" imports, without those imports deciding to use previously 
unused or unpopular tags.  It actually creates 2 problems - one is the 
"substandard" data, the other is that high tag usage values might 
convince other mappers (perhaps nudged by their editor, perhaps by 
looking at taginfo) to use more of the otherwise unused or unpopular tags.

Looking at the example data and comparing to the imagery 
https://www.openstreetmap.org/way/591832256 is clearly "substandard" as 
what should have been mapped as "a tree, on one side of the road" has 
instead been mapped as "landcover=trees, overlapping the road".  The 
other "landcover=trees" there both overlap each other and don't always 
match imagery.

Best Regards,
