No documentation that config options are aimed at servers
Maybe consider adding a reference to the package description that tells users that the config of the LTS kernel is aiming at servers.
I have found no official documentation regarding that, only some comments that imply that the linux-lts package is aimed at servers, like here: https://bugs.archlinux.org/task/75456
And default CONFIG_PREEMPT=y (low latency desktop) is not desired for LTS kernels.
And an old reddit thread that also found config differences that hint at the lts kernel being aimed at server usage: https://www.reddit.com/r/archlinux/comments/md4j2w/the_linuxlts_kernel_not_fit_for_desktop_use/
If the linux-lts kernel package is not aimed at servers at all and the differences in config has other reasons, feel free to close this issue.
