Why do you say that?  The rest I agree with; seems to me that making a
small wrapper for dict access works well, too.
I think it was tripping-up the folks working on the C implementation.  Georg can speak to it more directly.  IIRC, the issue was that the context object exposed a dictionary which a user could update directly and there was no notification back to the surrounding object so it could update an underlying bitfield representation.  If the current approach gets in their way, the C implementers should feel free to make an alternate design choice.
