No. When used for producing timber the trees get harvested - they are 
gone from time to time. So tagging the area as trees is incorrect for 
some of the time.
The landuse=* is about the use of the land .. what it produces for 
humans .. not what is presently there.
Adding landcover=trees to landuse=forest/forestry .. then what? remove 
the landuse=forest/forestry? And thus remove what some have correctly 

One solution is not to render landuse=forest/forestry the same as 
landcover=trees/natural=wood ... make it different in a way that people 
will see the difference on the map. Then they will start to 'tag for the 
render' and as th erender now shows that landuse=forest/forestry is 
different, say by adding an axe to the landuse rendering, from 
landcover=trees/natural=wood the mappers will be able to make better

If you can only see trees then tag the trees - 
Do not use landuse=* if you don't know what the land is used for ..
it is rather simple if you use the base language.
