[~e.dimitrova] will we need a fix in 4.0, since 2.0 sstables can't be read by 
4.0?

UPD: talked with [~e.dimitrova], and I was responding to a different question. 
I was speaking only about 2.0 upgrades, but am generally +1 to do the proposed 
"gossip" solution, assuming we're talking about mixed-mode 2.0/3.0 cluster or 
3.0/4.0 cluster that can might contain 2.0 sstables.
