OK, but you as the implementer of the Manager and of the most
important implementations of the Bean interface (for simple beans,
producer methods and session beans) can easily provide your own
internal SPI with *your* implementations of Bean, and *your*
implementation of Manager support. Is it *really* important that this
be provided for third-party implementations of Bean?

Really, I'm just asking the question. I'm not against adding this at
all, I'm just trying to balance the additional spec complexity
involved.
