This sounds similar to how Cloudflare Workers work - using the V8 isolate technology built for Chrome to provide secure isolation of backend processes without the overhead of VMs or even containers.

Yes. This is something like Cloudflare Workers (except we built a deep embedding of V8 rather than relying on the browser infrastructure).

Plus we have a distributed KV store to go with the code execution environment.

Our main reason for relying on the full browser is to not be tied to a specific browser engine, and to be able to benefit from browser security updates really easily, but there are obviously some challenges to this approach.
