I did this once for an experimental project and found it really difficult to keep the version of gVisor I was using up to date, since it seems like the API is extremely volatile. Anyone else had this experience? If so, is there some way around it that I don't know? Or did I just try it at a bad point in the development timeline?

That's just how Google operates in my experience... Avoid Google libraries unless absolutely necessary, and if you do adopt Google libraries, be prepared to either be forever multiple years out of date or spend significant resources on keeping it up to date.

Plus those libraries are often very hard to read and understand. Maybe I'm just dense though.

The API is indeed prone to change without notice, but it isn't anything terribly unmanageable.

For our project, we update gvisor whenever Tailscale does.

It could be that you happened to find a period of rapid change, but it is also possible that you ran into the issue that raggi mentioned in the sibling comment.
