I'm sure someone else has already said this (didn't read whole thread; CBA), but dude, seriously, start an alt/buy another account.
I'm sure by now you've seen lots of people mentioning why they see a clear save as a boon, not a bane. I have a free alt account for Horizons, but have a Lifetime Expansion pass on my main, and I don't see why I would buy that only to buy the game AGAIN.
Looks like I got the information I need: All ARX related stuff will stay, can keep the same commander name, previous discoveries will be tied to that Frontier account (but NOT the new commander even though it's the same name, which is as it should be), Holo-Me will not be saved (so take screenshots of the settings to recreate), back up keybinds just to be safe. That about cover it?
Interesting how the community is split on the very idea of restarting. Some are desperate to hold onto what they see as progress, while others feel they have reached the end of the road, so what's the point of holding onto that progress.
I've said it before in other places, a good thing for Frontier to add would be a "prestige" system. If you hit triple Elite, you can clear your save to start over, but certain things carry over (Holo-me, permits maybe) and perhaps unlocks some new decals/paint jobs... maybe an ARX bonus to reward/encourage people to start over.
