Well, for starters, magsafe is patented (making any 'official' copy hard to pull off) but 3rd party Chinese foils of magsafe are out there and I actually agree with the point that the SSD cart is kind of pointless.

*And making a homebrew standard doesn't really fly, especially for a startup like Framework. Thunderbolt already shares the same connector type as USB-C, and exposes traditionally internal PCIe lanes to the outside. Only scenario where Framework can actually make their own standard is if they genuinely reinvent a solution that had previously failed before like their just announced GPU connector that probably just made MXM look completely geriatric and obsolete overnight.
