AFAICT, no bytecode specification has been proposed for ES4. Tamarin's 
internal representation of ES4 (and whatever debugging it provides from 
that) are only related to the problem of debugging ES4 in the wild 
insofar as it becomes a successful implementation in the marketplace.

Right, but that doesn't address what to me seemed the primary concern of 
the original note that Erik forwarded, namely that it would be 
desireable if all ES4 interpreters/runtimes provided a set of unified 
interfaces into this data.

That it can be done on Tamarin today doesn't imply that the problem of 
handling debugging across VMs is solved. If we expect ES4 to succeed, 
there will be (almost by definition) many more implementations than 
Tamarin.
