Looks good to me, but what about regulators and other properties? Are
you planning to add them later?

No plan to add them, sorry.

I know, complete bindings are better than incomplete bindings. But in
the foreseeable future I don't need to do anything on the regulators
(even though it might happen at some point). And since their setting is
possibly non trivial, I'm not going to study them to write a complete
bindings document and then make no use of it.

Is it a problem for you?

It's OK.
