Based on BG's #20 post, things will remain as is. That's how I voted.
Guild-hopping being a "bad thing" in the current FS situation is, in my opinion, outdated. Personally, I would encourage it in terms of FS player retention. Times have changed.
The decision to leave and/or return are different from way-back-when, but I see no need to facilitate stats based on those options.
Some of my Guild's players lost their stats and have since come back. That fact is the result of a decision process.
For me, you're either in a Guild or your not. You can start over whenever as far as Guild stats are concerned.
