As far as I can tell Debian only has a single official powerpc port, 
supporting a wide range of hardware, for example.  It's not the only use 
case, but it is one case - hence it being useful to have the possibility 
of controlling the subset of multi-arch implementations built depending on 
what your particular use case is.
