[cdi-dev] Time to start working on CDI lite

@John, I'm not mentioning any runtime here.

In Java EE, the "fatter" JSR 330 will get executed in a Java EE container,
as usual, no need extra runtime. On the other end, when I use WidlFly Swarm
to build some tiny services and I need basic injection, I need the full
CDI. What I'm saying is, with a fatter 330, Java SE will have basic
injection, but also Java EE. I know modularity is not in the EE roadmap for
now, but it will be. When it's the case, you will be able to say "I want a
Java EE app with basic injection" (and you will only get the 330 module) or
"I want the full thing" (and will get CDI, which depends on the fatter 330)
