I am saying that *strict* backwards compatibility would not allow me to
change the implementation of a Component from Loggable to LogEnabled.
If we _relax_ that requirement so that only the role interface and
contracts surrounding it must remain backwards compatible, then I could
change Loggable to LogEnabled.  I would also be able to later add
Initializable, or remove Contextualizable.

For Components, the lifecycle interfaces are supposed to be different

so the vote is: Do we enforce *strict* backwards compatibility or *relaxed*
backwards compatibility?
