This is great news. I'm new to Resolve and have been struggling a bit, so any improvements to the workflow are welcome.
Unfortunately, a much bigger problem I've been having with Resolve is that it performs none of the automated corrections/adjustments that ACR does. In my case, this means my unprocessed 5D3 RAW images have intense chromatic aberration across the entire image.
I asked how to fix the CA on both the BM and ML forums. The responses I got seemed to suggest that most colorists improvise their solutions. I certainly understand why Resolve doesn't automatically fix this yet (it requires a huge library of lens profiles). But the prospect of creating my own CA fixes for about a half dozen lenses gives me pause. At least they could have a tool that puts you in the ballpark (or a tutorial... or something helpful).
Far as I know, the two major advantages of Resolve over ACR is speed and dealing with motion. ACR has no motion capabilities; which obviously means it's not a pro tool. Period. But ACR does have one big advantage, which is that it takes about 2 seconds to get near-perfect grading on any random, low-motion footage.
The frustrating thing for me is that most of the Resolve interface and tools look pretty straightforward and manageable to learn. But there's a few stumbling blocks that even experts struggle to help me with. Oh well, suck it up I guess.
