Okay, but 6.1 is still from December 2022. Like... it's an improvement, but as my desktop sits at 6.19 and 7.0 is impending, I have to question why they lag so much.

OP was talking about that they now have and pursue the intention of upgrading the kernel during the lifetime of the device. Instead of device launching with LTS kernel, which is supported for many years upstream, and always using it, instead LTS kernels are supported for 2 years (or extended like here), and the devices keep moving on to the next lts branch during their lifetime (usually not immediately, but after the regressions fixed for next branch, tested well before that in avf VMS etc)
