I am not in favor of changing the usage-requirements to propagate all
the way. Regarding the previous example of libraries A, B and C that
have the following chain of dependencies
lib A ;
lib B : A ;
lib C : B ;
I do not think that this setup says that C uses A. If library B includes
some headers of library A in its public interface then it is the
responsibility of library B to say that the usage requirements of A
should be propagated further (lib B : A : : <use>A ;). I think it is
better to be explicit in this case because it is more predictable and
does not cause unnecessary bloat of the final command line.
