100%. I for one won't be buying a Gravity if it first comes with CCS to then change to NACS later, I'll wait for NACS. I think I read somewhere it will come with NACS but if shopping for a new vehicle now I wouldn't be buying one even when promised an adapter. No one knows the true speed these adapters can deliver so if they're limited to 150Kw and your car is capable of charging above that then buying a CCS car with a NACS adapter isn't helpful to you for years to come.
If you wait for NACS, then you might be stuck using adapters for a long time. Even without an adapter, Tesla's current Superchargers won't charge a Lucid at above 50kW. Plus, the cables won't reach. Existing CCS chargers are extremely unlikely to have NACS cables. So if you get a Lucid with NACS, unless a lot of things change quickly, you will need an adapter.
On the other hand, if you get one with CCS, any V4 Supercharger will have a Magic Dock anyway, so you won't need an adapter. The adapters are passive and should not affect charging speed. You would still be able to use other third party chargers with CCS, and as they add NACS, they aren't going to be taking away CCS. So you are unlikely to need an adapter with a CCS port, but very likely to need one with NACS port. The exception would be if you don't mind using a Tesla Supercharger at 50kW, in which case it will take over an hour to add 200 miles, as opposed to 12 minutes from empty with CCS at 350kW. And if you need to use a V3 Supercharger, you'd need an adapter but that's the least of the problems. The cables are too short and they are too slow, and if you want to save a few seconds by not needing an adapter, you won't save much. The infrastructure bill requires any future chargers to have CCS anyway, so for the foreseeable future, any new compatible high speed chargers won't need adapters for CCS cars.
I was in a similar position when I got my Lucid. Tesla had opened things up, one manufacturer after another had agreed to switch over, and Lucid hadn't. At first I thought that I'd wait, but after looking into it, I decided that I was better off not waiting. I'll get the adapter when it comes out. But I doubt that I'll need it much if ever. If I had a NACS ports, there would have been a slight advantage for home charging since it would have been the same as on my Tesla, but the Lucid came with charging equipment anyway so that wasn't a big deal. For destination charging, with a Tesla I had to use an adapter about half the time anyway. The same might be true with a Lucid.
