It hardly is the better way. The key landuse is contaminated with a
lot of values that simple don't fit or are used in an inconsistent
way. Most prominent example for sure is landuse=forest, which
currently is used in case the land is covered with trees. But this is
not a landUSE. If the land is used for growing trees than
landuse=forest is correct, but there may not be any trees at all at
the current time because they are just being planted (landuse=forest +
landcover=grass). On the other hand there could be a lot of trees but
completely unmanaged (landcover=trees + no landuse).

That's the main reason why landuse (and also natural) needs some heavy
cleanup which of course would deprecate some tags and for sure take
some time. But I don't see any other way.

I started an overview on my user page of the current usage of
landuse/natural and how it might look if we use landcover. If someone
is interested take a look.
