a bv-implementation can use a default implementation (which isn't
configured -> it gets instantiated manually).
such a default implementation aggregates the configured versions.
e.g. if you have cdi + spring in the classpath, only one will return a
result. as soon as an implementation returns a result, the rest can be
skipped.

In most deployment scenarios, I wouldn't expect more than one to
be
available, so it should simply work. In case more than one is available, we
should probably fail with an exception.
