The removal of the mirror places the RF mount 24mm closer to the sensor. There is no way to retain infinity focus for an RF lens mounted further than the 20mm flange distance of the RF mount. Although the flange distances differ across vendors, no mirrorless lens will work on a DSLR. But in all cases, the legacy film / DSLR lenses can be adapted to mirrorless bodies, without regard to vendor / mount, as there's around 20mm free space for various vendors to introduce the mount adapter.
Excellent point, I’d forgotten about the physical space problem.
