Just a quick follow up, the part of this statement that to me is wrong,
is it appears you are dictating work flow. While, imho, the layer
management code which is above this level, is the place to dicate
workflow. The patch is to core bitbake and isolated at that. This patch
adds an additional work flow, and can be used in either state(the
results of a current BBLAYERS setting is exactly the same today as it as
after the patch).  More or less the patch is useful in a scope larger
then just layer-tooling.
