If you want to have a binhost, then --changed-deps will become
"necessary" at some point. Let me draw you a picture, where a binhost
would fail to provide the correct package:
 - Binhost builds on day 1 package XYZ
 - computer that would merge with packages from binhost is NOT updated
 - the dependencies are changed on day 2
 - Binhost does NOT rebuild, because you do not have --changed-deps
   enabled on day 2
 - Computer that merges from the binhost is updated on day 2 but will
   NOT use the binary package from binhost, because the dependencies do
   not match
There are flags to ignore dependency mismatches, but the default would
just not use the binary package.
