Then you would at least get failure or a working package.

Just  because  a package builds without failure doesn't mean it is the
intended build. A less desirable case would be a package with optional
build  dependencies,  that  gets  built  with different configurations
based  on  the  presence  of  extra packages that happen to be in that
cached buildroot.

Having the required packages for build and no more is important.
