Thanks Steven, I hope to! The pressing issues were (a) holster for it and (b) screen protectors. I have used Armorsuit Military Shield protectors for years and swear by them...
but they don't make protectors for foldables. It's tricky business making glass bend: it's equally tricky to make a durable skin that glues to it and bends with it.
The holster? It was actually pretty easy as there are two-phone holsters out there. I found one I like, and the comments said that their Fold 2 fits in it nicely. Since the Fold 3 is a bit smaller & thinner, it follows that the Fold 3 in a thin case will fit in there. It sticks so far out from my waist, however, that I may have to walk sideways to get through doorways... but that's the price I pay for being on the bleeding edge of tech geekdom, I guess...
