As a minor feature request for the next DS version, it would useful to allow Optional as a supported field/parameter type for an optional service reference. For example:

@ Reference
Optional<LogService> optLog;

It could be inferred from the type that the reference has cardinality 0..1 rather than 1..1. When the service is unavailable, the field would be bound to Optional.empty rather than null.

This is actually a very good idea.
Any official opinion/feedback on Neils request?
