Canon has no issues with 3rd party lens makers using the RF mount, as long as they are not auto focus. For example:

https://www.amazon.com/Venus-Laowa-100mm-Ultra-Macro/dp/B0851QX7X5/ref=asc_df_B0851QX7X5/?tag=hyprod-20&linkCode=df0&hvadid=459520431986&hvpos=&hvnetw=g&hvrand=12831240384456788797&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010332&hvtargid=pla-909495837553&psc=1

The 3rd parties are just "dumb" lenses without any electronics. The key difference with the Cosina is the electronic functionality of the lens. The new Cosina lens may be manual, but has full electronic functionality, meaning, EXIF data, in camera auto corrections and IBIS, probably aperture control (EF Cosinas have this), and use of Canon manual focus assist features.

I know Samyang and maybe another manufacturer had electronic lenses before, but were probably using the old EF protocol or reverse engineering not quite compliant with patents/intelectual property of Canon.
