Still seems they're ignoring to fix PDC mid-chain though. It's the one thing I check to see if they bothered with on every release, but I won't hold my breath.

That’s obscure but we’re on HN so I’m here for it. Live isn’t alone here; you won’t find mid-chain delay compensation in other prominent DAWs either, for instance Logic Pro. The usual workaround is to keep high latency plugins later in your chains, or put them on separate returns. A real fix would probably require every device to get its own offset clock. That could be a lot of under-the-hood work (and new UI confusion?) for gains most users won’t notice. They fixed automation delay compensation a number of releases ago, so I guess this never quite hits the top of their priority list.
