Honestly? It is.
Getting a understanding of what you do is something that is moving towards “lost arts” territory regarding everything computer related.

In reality, what Chromebooks provide is a reinvention of the good old mainframe and terminal principle. In theory (like my recent - half joking - 9front comment) this is something that would be really easy to set up with nearly all Linux systems and especially immutable ones.
My take would be:
Put an sign up / sign in form as a “first boot” message in a distribution of your choice where you can specify (or have pre-filled by an organisation) a central server (could be something fancy like Nextcloud or something simple rsync based) where your whole profile folder gets synced to. After that: If anything goes kaputt just roll back the sync. Or “powerwasch” (to keep the ChromeOS terminology) the system to a clean state and re-sync your home folder.
In theory something that could all be implemented with a little scripting in an afternoon.
9front (with enough volunteers and a modern browser) could be exactly that.
