I thought that the static dispatch bit later on in the proposal implies that that wouldn't work so well, but I might have misread. 

If the proposed changes are built right into the protocol, the dispatch is dynamic. If they were added via an extension, then we’re stuck with static dispatch unless some changes are made to the language (which is also possible).
