Description
As I understand, there's currently no standard for passing values like the log-density or log-weight (when that exists) for each sample. Algorithms that require these will each have to come up with their own standards, which will then need to be managed separately.
I have some description of how I'm handling these one instance of SampleChains here.
It would make things much easier if things like this can be standardized, to the extent they're common across samplers.

Research direction
Start with the SampleChains handling described in issue #57's linked comment and review how per-sample log-density, log-weight, and other metadata are currently passed. Define a common standard for metadata shared across samplers, with the scope and compatibility expectations agreed before implementation.
