I think a big question is whether we want to save 10.0 for some incompatibility changes, though we didn't do that for 8.0 or 9.0.
Someone (can't remember who) suggested a good time is to do it when we can allow actual zero-or-close-to-zero-downtime upgrades.
While having parallelism is awesome, it's only going to affect a (arguably small or big depending on your viewpoint) subset of users. It's going to be massive for those users, but it's not going to be useful for anywhere near as many users as streaming replication+hot standby+pg_upgrade in 9.0, or pitr+windows in 8.0. And yes, the vacuum freeze thing is also going to be great - for a small subset of users (yes, those users are in a lot of pain now).
I had a discussion with Marko T just a couple of weeks back, and the conclusion then was that at the time, 9.6 had almost nothing that would even make the cut for a press release. We now have these two features, which are great features, but I'm not sure it's enough for such a big symbolical bump.
