Sorry, I'm wrong -- that doesn't show the problem. ASI only inserts on an error, and there's no error there. I thought there was a case not covered by ES3 that would parse yet change meaning without ASI, compared to with ASI. It looks like there is no such case, so you're right that only parse-ability needs to be tested.
That still means work for someone, possibly dealing with thousands of lines of code written by someone else. It's still an unmotivated migration tax.
Again, what problem are you trying to solve by removing ASI from strict mode? You didn't answer last time I asked.
