As mentioned in the link, I too find “Zoom Tracks Exclusive” absurd. But using “Enlarge Selected Track” by key command is still clumsy due to the constant notifications.
It’s also worth mentioning that “Enlarge Selected Track” lives under Key Commands>Preferences, but also under Key Commands>Edit.
I don’t know if someone put it under Edit hoping to spare us the notifications (of changing a preference by key command), but from what it seems it didn’t work. Both key commands are identical in function as far as I can tell, and both trigger the notification.
