The solution to topic from 3 years ago still stands:
linux-meta is a good safety-net to help new users that do not yet understand what an EOL kernel is or how to manage Manjaro Kernels
I asked about testing this metapackage recently and was advised that it was not needed
So there should be very few problems for new users when kernel 6.10 an 6.11 are dropped
and 6.12 becomes the new LTS kernel
