In this case, it's not language lawyering. All JavaScript environments "do the right thing" with regards to ASI -- it works in all target environments as of the present day. JSMin is not a target environment, it is a minifier that happens to express some strongly-held opinions of its author.

That said, it's hard to program to a spec that does not (officially) exist yet, and doubly so if there's not clear "opt-in/out" path for future versions. Since, as a developer, I can't control what the committee adds or removes from the spec, or what they might break, I can only do the best I can with the language as it is -- not breaking existing code in future versions of the language is the committee's job.

If JSMin is not among their target environments, they should not use it.
