Not only is it distracting for the community, but the core team and many others won’t be be able to even read the thread or the responses, thus your discussion cycle will be lacking key input.

Right. If you're interested in pursuing something like this, you might pitch a proposal that adds a "reswitch" that takes an operand to re-dispatch on; but like Chris says, you should wait until the Swift 4 cycle starts.
