No-one is going to manage to change all the BUILD_DEPENDS overnight. 
So until each package is split out into constiutuent dependencies, the
only information that some packages may have is BUILD_DEPENDS.  For
packages that have been split, though, there will be the tool depends,
and the link depends packges (whatever their names are).  Aggregated
together, they make up BUILD_DEPENDS.

In other words - it is a way of reaching the goal while making
incremental steps towards it, avoiding flag days, and generally
providing finer-grained information.
