No, I wasn't aware of JSR 365 (nor similar requests).
I don't have any plans (nor am I aware of any plans) to incorporate any of the proposed features into Guice.
Guice has a very opinionated view on what it does: it's a lightweight dependency injection framework... and that's it. I don't believe incorporating the CDI specs into Guice would be in the user's interest. Guice offers a number of hooks that allow extensions to expand its surface area, and enterprising individuals may be able to utilize those hooks. The core of Guice, however, is going to remain simple so that users can have a reasonable mental model of how things work.
