I don't currently have the time to digest this email in detail, but I 
wanted to mention an alternative you didn't before I forget: Making the 
exception an in-out parameter. That would be functionally similar to a 
return value, but more strongly default to “don't make a change”, 
because “doing nothing” will just work.

i.e.

     public function exitContext(?\Throwable &$e): void {
         // Assign null to suppress.
         $e = null;
     }

Best regards
