I used the Camera Callibration feature on Lightroom Classic on almost every photo I edited. I loved that feature, and I'm really sad to see that they removed it. I really hope the feature returns in a future update.
No worries, Jonah. Lightroom CC is not an update but just another tool in Adobe's photography suite. Check out Lightroom Classic which is the update for the previous Lightroom and you will find all the tools you know and love with a big boost in performance.
Lightroom CC will continue to evolve and who knows what features may end up there. Stay tuned!
I'll change your post to an Idea so it gets logged as a feature request.
