Can you be (much, much) more precise?  Mainline Linux can easily be
tuned for different deployments already.  See Fedora spins, or more
specifically, Fedora power profiles.

Is there something (again, be very specific) that requires a different
kernel package?

The experience with Debian is this is a lot of work, with a negligible
userbase.  People can already run a Fedora userspace on top of other
Linux and other kernels.  For RISC-V, I sometimes have to run Fedora
on top of vendor kernels with lots of weird non-upstream nonsense in
them, but I don't expect Fedora to support me in this endeavour.

IIRC the two cases that make the most sense are installing a mainline kernel and a LTS kernel. The LTS kernel usually being useful if the main Fedora kernel has issues.

AFAIK both can be easily installed via COPRs though. So, I don't know how much it would benefit from official support.

Thanks for your time,
