And yet, per the spec, new syntax features are allowed to break ASI:

> As new syntactic features are added to ECMAScript, additional grammar productions could be added that cause lines relying on automatic semicolon insertion preceding them to change grammar productions when parsed.

So really, the rules are “there are currently 2 exceptions and an infinite number allowed to be added at any time”. To me, that’s worth letting prettier auto-insert semicolons when I hit save.
