Whichever cassette is used dictates which mech and chain are used. Red AXS cassette = flat top chain & Red AXS mech. Eagle cassette = Eagle chain & rear mech.
Yes, that's not in question.
Provided your chainring is 12s you are good to go.
Except that's not what SRAM say. Look at the linked Q+A above. It says "Red eTap AXS chains are
ONLY compatible with Red eTap AXS chainrings."
Personally I think that's probably wrong, and Red chains can be used on Red or Eagle X-Sync chainrings that same as Eagle chains can be used on Red or Eagle X-Sync chainrings... but as I said their communication regarding the mechanical compatibiity is very, very bad.

Why? What’s the point???

No, for two reasons. First, if you're thinking of 2x those chainring teeth are only supposed to be used with the Red chain. The 1x teeth are different. Second, the derailleur pulleys are matched to the chains. So theoretically you could match a KMC chain, Campy cassette and
Eagle derailleur, but why would you? However, nothing about the stated compatibility implies you could run a non Red12 chain through a Red12 mech and achieve acceptable results.

AXS will have a different chain pitch interaction due to the different roller size. Put smaller rollers into those teeth and wear/chain suck is not going to be pretty....

Haha, I thought someone would say that, allow me to clarify;
Not in countries where people can afford to buy bikes with Sram on them.
Well, here in Austria we have a dense logging road network that probably rivals tarmac roads in size. I can't (or won't) afford eTap AXS however, and I'm perfectly happy to ride all roads with mechanical gearchange.

Gravel won't take over the road market for the simple fact that most roads aren't gravel.
Most roads actually are gravel though.

In the middle of the US most roads are gravel. We're also down to a handful of road races a year but there are multiple gravel races every weekend.

I did an event yesterday morning that could be loosely termed 'gravel'. This was in the English countryside in February after a week of heavy rain. The trails were an utter mudbath. Is anyone really going to want to subject £2k of electronic components to that?

Right, the emptiest part of the country.
And not only does the racing scene not really correspond to the riding scene in any given place, gravel races are to a large degree more like events, right? To fairly compare you'd need to balance gravel races against road races, sportives and gran fondos, IMO.

It seems DT Swiss aftermarket XDR drivers are available everywhere now, but has anyone seen 240s hubs for sale pre-configured as XDR? Need to buy two hubsets and would rather not pay for the default HG11 freehubs if I can avoid it!

Norway, Sweden, Finland. All have extensive gravel road networks. And moderately high disposable incomes.
Except round here, the gravel roads are generally in better condition than most of the rural tarmac network in the UK.

The fact that it's electronic is actually a very good reason to choose it.
The fact that it's all top level kit is a good reason not to........
I'd far rather, say, Ultegra Di2 (even hydro discs!!) than mechanical D-A on a proper slopfest of a ride.

Some bits are relatively crowded, and have lots of gravel roads/trails/tracks. Some bits are desolate, and have less gravel roads.
Unlike the UK, which is crowded and mostly has shit tarmaced roads.

Ok, cool - so every single road rider in Scandinavia is going to convert to gravel bikes. What's that going to do to SRAM and Shimano's global numbers?
