I cannot say this for landuse=meadow since i have not looked at these 
but for natural=rock and natural=scrub the thing is this data is 
usually just pointless even if there have been local attempts to 
improve it, simply because the premise of the CLC data that there is an 
area with more or less homogeneous properties is not fulfilled.  In 
such cases any attempt to move the boundaries of such a polygon to a 
more accurate position is doomed.

In defence of the CLC data - there are similar cases elsewhere based on 
manual mapping which are equally questionable.  For example around here 
there is frequent use of landuse=grass like

It would be equally right to delete those IMO although i am pretty sure 
this would be considered vandalism by some.
