If it takes more than a couple of hours for an exchange to do an update to a software program, then it is not a very efficient system I guess, I do not know how long it takes to do their updates. I do not know a lot about crypto currencies, I know a lot of the other block chains have a lot more HF's than Steem. The first year for steem saw 19 HF. I have been on steemit for just over two years HF20 was the first I went through, was anyone concerned about the number of HF's in that first year?
On Friday what happens if Busy.org finds a bug that effect them? Will their request for a HF23 be passed over? On Tuesday when the first payouts from HF21 start to come in and if things go bonkers during that time frame is it going to be because of HF21 or HF22? If you wanted to delegate SP to some one right now you could do it. Are we expecting the witness to just blanket approve this HF22 with out testing it or even looking at it? It took over two months for the witnesses to look over HF21.
I think they need to continue to evaluate the fork, and watch for other problems before just blindly, (that is the way it seems to me), throwing up another hard fork. I can delegate steem and if I can delegate then almost any one else should be able to. So to me this seems strictly a Steemit Issue.
