I feel its likely the marketing verbiage w.r.t. repairability was targeting the average "prosumer level repairability" - which is probably more closer to an iFixit level of repairability (i.e. more on the torx screw and less on the solder/depop spectrum of repair) [1].
That said in response to these HN and Youtube threads - perhaps they could update it to be more specific about their definition of repairability as well as why schematics will be or can't be released.
In the future - if Intel is the issue - it might be smart to design some additional modularity and relegate the proprietary Intel stuff to some sort of system on module (like the RPi4 Compute Module) and increase the amount of open source able main board.
It seems likely that the 'module' would just cover the entire space of the board as-is if they did this with a modern intel system anyways, especially when there's also SODIMM module slots, an m.2 slot, and 4 full tb4 ports on the board.
All those high speed bus interfaces are probably tied directly into the CPU, the chipset, or both, and so are largely gonna be covered by any confidentiality agreement intel imposes on vendors of those parts.
The Pi4 CM is a much more modest device by comparison. It has no ram expansion and only a few lanes of PCIe, USB3, and some other fairly standard IO interfaces otherwise.
Realistically, the frame.work mainboard is the compute module. You plug it into the equivalent of a CM carrier board with the TB4 ports.
