One q: why are you building a code running/functions platform inside your project, sounds very overdone and not related to your project. Also scary as a customer. I would recommend just make people host workers, we'll need it anyway to access resources, VPCs, etc.
I can understand being skeptic about that but we did not invent nsjail nor linux forks so it's pretty simple and rock solid: take source code, wrap it a little, execute it with python or deno. As soon as cloudflare workers is open-source, we will provide adapters. We did not have much alternative to make it easily self-hostable but interested to hear your suggestions.
