This isn't a case where systemd is ahead of the curve, every other OS also starts services in parallel.

That said, parallel startup is possible on those systems too. There was an out-of-tree patch for parallel rc(8) on FreeBSD some time ago, and dinit is parallel, etc. I think OpenRC should move towards making parallel startup stable and supported so that those systems can do that as well.
