they are talking about copying a block like bitcoin did. So you would have all your SP here but you would have new SP on a new blockchain. like when the bitcoin split, you still got you bitcoin, but you also got bitcoin cash. This would work the same. And I hope they accept you, you have became a much better member of the community! I vote for them to let you opt in if you feel like, I dont see any reason they could deny you. You didn't premine so you should be all good
