I am glad that Canon decided to go the adapter route for their FF mirrorless. The control ring adapter was my wish for the last 5...10 years, it came true. A tilt adapter would be awesome especially with DPAF where you can choose the AF area easily (or two AF areas to adapt the f-stop automatically). A shift adapter would work for EF lenses and APS-C area readout of the sensor.
While some soft focus adapter is not a primary need for me it shows that Canon might increase the numbers of options - maybe a good long-term differentiator against those who gone mirrorless FF directly where you haven't these options.
EDIT: Forgotten to say that I do NOT see any need to go FF again (after a 3year excursion with 5D i) because M50 with EF-M 32 is a killer combo for those who like it small / light / close focus / with very high IQ. But the adapter solution makes the R system attractive to me to use my EF lenses with f-stop ring (their worst amputation compared to FD lenses) and my small set of FD lenses maybe for artistic / sentimental reasons

And if I need or want FF I will buy an R system camera - e.g. an EOS R50 (M50 like system) for 1300 EUR !
