Why if the current kernels work fine then i have no reason to use it. My system doesn’t break all the time from updates so i have no concerns about that. If it happens i deal with it at the time. I use btrfs and btrfs-assistant with snapper-support and btrfsmaintenance. I’m good. I have no problem having lts as a backup but I’m just saying for me I have a different philosophy. I wouldn’t be using a rolling release distro if i always needed to be using an lts kernel. To each their own. 
Edit: Worse comes to worse i just reinstall in a few minutes I’m back.
