Maybe it's time and distance, or some kind of Stockholm thing, or maybe just the jones for SR that will probably never really leave me, but I am giving SR6 a second look.
To my surprise, it's not as bad as I remember. I'm actually considering trying it now.
I started out by trying to make a starter template for a decker, something myself or others could use to create a straightforward generalist decker that is rules legal to replace the one in the CRB, which (as best I can tell) still is not in the latest PDF. I then decided that a quick explainer that walks people through how to be a decker would be helpful. I usually have to introduce new games to my groups with pre-gens and cheat sheets, so we can all just sit down and play. As I went through, I found I was starting to get a better sense of how it should all work together. By focusing on just "how to be a decker" a number of challenges went away, and by aiming at teaching a new player how to do things with Edge, that wasn't as onerous as it seemed previously.
I still wouldn't advise any fellow player to spend money on the product, but I think I might be interested in running a game to see how it goes.
So, despite everything, I find I am diving into 6e after all. Spirits help me.
