He briefly mentions rtinfo then says it's not part of the talk, 
is RTinfo actually used for anything? AFAICT it's just a dummy 
value at the moment.

No, it's an experiment to see what people will do with it.

The problem with actually using it for any features right now is that 
people may get used to the reflection data included, and we haven't 
figured out a good way to make it extendable to user code. So it's 
difficult to have some "official" implementation.

IIRC, the point of adding it was to aid in creating metadata for the GC 
to use during collection for an allocated type (i.e. precise GC).

Yes, it is just a dummy value in the upstream druntime repo, but 
people have been changing it in their local copies for precise 
GC, some forms of runtime reflection, or more crazy ideas (see 
Adam's work).
