Changed to General. Instead of asking for developer intentions, which would be unknown to forum volunteers, the question is answered since Z16 is already at requested kernel.
@hcmendez - could you please mark the response as the solution?
Installing a newer kernel then the one that Zorin OS 16 comes with, could cause you a black screen of death. Good news however, if it does, you can revert to an earlier kernel in GRUB if you do.
I am having the opposite problem, I updated my OS for kerne 5.13, but GRUB doesn't have the new kernel listed, so I am stuck on 5.11.41. I am waiting for the Zorin brother's to fix that, as Aravisian and I haven't found a fix for me yet.
