This is exactly the idea behind that setup. My OS will be Arch Linux which is a rolling distribution. I have some years of very good experience with it on my development machine and I love to have the newest and supported software/kernel/libs it is providing.
For these very rare cases in which the system update will somehow hurt something I need the LVM snapshots to get me running again pretty soon if needed. I bought double hardware like motherboard/processor and will change disks at latest after 5 years. The system is supposed to run for 10+ years and will host some virtual machines based on KVM (one of them is from 2006 :-) running ubuntu LTS, totally outdated but always there, when needed, guess the next 10 years, LOL).
