I don't expect 50/50 to work but I'm in favor of trying things out. However we don't really 'try something out' when we hard fork, we end up committing to that change because changing back would be another hard fork and a whole bunch of work just to get us back where we were.
We need some kind of trial period with a rollback at the end. That way we only continue with the new economics if we specifically elect to.
It is just so difficult to get everybody agree on something, especially the high stakeholders.
