I’m also going to leave this here; my own saga/perspective and reasons why your hunt for a magnetic charging solution will likely be fruitless in the end:
I think the only realistic hope would be if Framework were to work with a company to design and manufacture a high-quality magnetic charging expansion card of some sort…and even that isn’t very realistic given the small return on R&D investment it would yield for them. Apple has invested millions into their MagSafe 
design over 3 generations and they don’t even (officially) support data over it…but they also have millions of customers to sell that feature to, which justifies their investment. Framework just doesn’t have that kind of inertia behind them.
