It is not my experience that keyboards are part of their garden wall. I have used bluetooth keyboards with my iPads going back to the first generation of iPad Mini.
What their keyboards do offer is tighter integration. That’s not a wall, it’s more like growing enticing apples in the orchard within the garden.
Not much different than the situation with upgrades for my Volvo. The Volvo stuff is tightly integrated. OEM stuff sometimes involves compromises, like plugging things into the port and fiddling with bluetooth.
