blocks arrive faster meaning there are enough hash there, so it's not a bad thing
In general, yes, but due to the qwirky nature of REQ-7, there was a brief window of opportunity to reduce difficulty by an extra 20-60% over the next few blocks. By mining just a little bit too quickly, we missed that opportunity and will likely have to work our way through 786 blocks at the higher difficulty until the next retarget.
It would have been far more profitable for Bitcoin Cash miners if they'd have just paused for three hours or so. This would also have given us significantly faster blocks for a week.
Technically, we could still catch the tail end of this opportunity, but it would require us to go a couple of hours without seeing a block. We can't really expect this at what is now 50% difficulty but maybe we'll get lucky.
