We could also make it a protocol message, but it would essentially
implement the same thing, just again separately. And then you'd have no
support to inspect the current setting, test out different settings
interactively, etc. That seems pretty wasteful and complicated for no
real gain.

The list is what the list is. I don't see how you can make it any
shorter. You have to list the data types that you're interested in
somehow. Any other ideas?
