Nice to see such a discussion around this and some strong points. There are some heated points so lets hope whatever the outcome we all respect the community decision and move on.

Seems like all 3 should be separate proposals.

Personally:
1-Yes
2-Partially. Only if you purchased outside the presale by mistake. If you purchased inside the presale it just opens an avenue for exploiting the SPS gains since presale
3-Number 2, if only for outside the presale, provides a solution already and makes this option redundant
