For me, a Light version of CDI is clearly the features number. That's why I
don't see events in it.
For me, a CDI Lite would just focus on DI. If CDI has @Produces and Spring
has @Bean, then it's because 330 lakes this functionality.

Lite can have several definition, let's try to list them up if it
can help:
- binary size: for me until 3M for an app it is "Lite"
- features number: the whole IoC set of feature is light since you almost
always need it, it means you can do lighter but it wouldnt be used - check
spring, who uses only spring-ioc and not context or more?
- features complexity: sure we are not light here but supporting scopes
already breaks "Lite-ness" IMO so not a real issue
So my view is CDI "SE" is light enough - as a spec and spec can't affect
implementations so seems the fight is not on the right side to me.
