As Dimitri noted, I've expressed mild concerns about this in the past, but
I may be coming around to the idea. The main advantage of using Symbols is
that it would guarantee us the ability to add new callbacks in the future
without fear of breaking existing elements, though I don't know how
realistic a concern that is given the "Callback" suffix all these names

Do you have a proposal for where these symbols would be vended? In ES,
builtin symbols are available as properties on the Symbol object, but
clearly WebIDL shouldn't be adding things there. This might be a good
question for public-script-coord.
