Not everything needs to be molded into a common base that serves the needs of all. Fuchsia has different constraints than the ones gvisor is written for and choosing to not try to morph gvisor into something it doesn't want to be is okay. Optimizing to solve problems should be the goal. Sharing code is nice to have where it makes sense.
The context here was that gVisor was a suboptimal way to solve the problem and they know that... so I am not sure in what point you are trying to make by saying people can optimize to solve problems unless you actually mean people can optimize to not solve problems.
