You're making the fix way too hard. The solution is just to change "that maneuver is" to "all maneuvers are"
The problem is that FFG hates making text changes to cards. They're FAR more likely to make some completely baseless left field ruling that makes no sense.
I think Vanor's mostly playing with his crystal ball here - not reading or interpreting the card, but guessing at what they'll do to fix it when they realize how crazy the combo is.
It's not like they've never done it though. Daredevil comes to mind... also Expert Handling.
