Going to build up an ADHX for the purpose of an "all-road" build. Something like 98% road/2% gravel if I'm being honest with myself. Essentially something that will work nicely with 35mm gp5kas tyres (or something similar..) so I can be comfortable over the crappy chip seal we have here and a couple of bike paths I'd like to take that turn to very light gravel half way through. Still deciding on wheels. Was going to go Reserve 42|49, but now these new GRCs are out, I'm thinking of these in 50mm.

Anyone have any thoughts on these as "all-road" wheels?

I was thinking the same thing - only thing right now is availability. They should be very fast with +30c tires.

I have similar needs (one wheelset for everything but 95 percent road on lets say 32C tires) but not sure what wheels to take. As I will be mounting that on an endurance bike I want something light to add some snappiness. I don´t want to sacrifice aero and looks (56 size bike needs certain rim height to look OK) so I believe something around 45mm is a good compromise. Maybe carbon spokes is a nice feature for the snappiness and lightness.

I can choose something like CRW CS4045 but it is just 21mm wide internally. It won´t match 32mm width of the tire, on the other hand very light wheelset sub 1200g with 350g rims - they will offset the added weight in the tires compared to 28C.

Or you can choose something wider with around 25mm internal width to better match tire width but it will be heavier so not as snappy.

Those Reserve 42/49 wheels have nice specs but I don´t see them being sold anywhere...hard to say how they are and when they become available...

I was looking at the ERC, did you check those out?

They are 1450g at 45mm rim height and 29mm outer width. It seems to me quite heavy. CRW4O45 are sub 1200g. Magene Exar DB405 are around 1300g...those Reserve 42/49 also much lighter... many many wheels are actually much lighter... I would say they might be OK and reliable wheels with nice hubs but I see nothing spectacular about them...

GRC is a bit overkill for road use, ERC is more like all-around.
You'd probably want to go for 1100 variant instead of 1400 because it is really really heavy. The reason is that DT's carbon rim is somehow much heavier than other brand's. So, even with top-tier DT180 hub, the 1100 model still don't have too much weight advantage over other top-end wheels at the same depth.
Still, I do like DT's wheel building quality and hub enagement feeling. If you find being 100g more than other top-end wheel is not a big deal, DT is just fine. Very reliable and cannot go wrong.
Width-matching is not really a thing for fatter tires in my view. You will need a stupidly large outer width in order to totally match the width. Besides, if your starting point is 'all-around', then you can safely forget about these aero BS. Going for a 60mm deep rim probably only gives you less than 5w of aero gain, not to mention some very minor aero loss by not exactly matching the width of tire and rim.

I was previously looking at ERC 1100/1400. Unable to find suitable stock and just went for a pair of ARC 1100. 28c fits the ARC 1100 without issues. I'd expect similar smooth user experience with ERC 1100. DT's wheel building, particularly the spoke do feel really good. Noticeably more agile then my zipp 404/303. Hub is smoother than normal pwal rachet hubs during gear shifting, and the wheel engage firmly when you push it, solid and instant. I might recommand others to went for these wheels with extra weight savings and other gimmicks. But I don't want mine broke down in the mid of the road. (My zipp did this once, the freehub bearing simply stucked.)
