deployment framework that has any number of deployers operate on a deployment. Correct
startup order is a function of deployers adding the correct dependency metadata to the
kernel deployments they create. Any deployment package level dependency control would seem
to be an aspect/deployer that used its own metadata to create place holder kernel objects
(or used equivalents from jsr77) to introduce coarse grained dependencies. The question
is, is this assement correct, and do we need such a coarse grained deployment
aspect/deployer?

I'm not sure I understand this?
The deployments contain many pieces of metadata that are deployed
in an aspectized way. They still need an ordering, but based on the
metadata rather than the deployment suffix.
e.g. aop must be before classloading, classloading before
"instantiation", etc.
Other dependendencies (between services and entry points)
should be via the microcontainer. We are trying to remove
the implicit dependency of the suffix ordering and replace it
with a semi-implicit (i.e. added by deployer) dependency.
e.g. If an ejb uses another ejb/datasource then the
"enc/resource/reference" deployer adds this.
e.g.2. Trivially, the above also requires a dependency on naming
e.g.3. A web deployment has a dependency on the web container
etc.
