I do this for years. but instead of docker I use LXD (even for GUI stuff). my base system is always clean and idempotent (chezmoi). all my clients look the same. laptop, desktop workstation, etc. I even have a portable LXD environment which always looks the same, on a USB flash drive. wherever I go, I have the same environment.
