I believe last year on the 17.XX betas they had an RC, RC2....and even changed in the public release. I forget which ios 17 beta that was---so it's not a guarantee like you correctly stated above---- "RC is not always same as the final".The fact that installing an RC still includes the Feedback app always makes me think that it’s still operating on some sort of beta level, so my OCD usually forces me to wait for the official public release.
