Yeah, with plain Kubernetes I'd also see the practical limit around ~0.5s. If you are on GKE Autopilot where you also have little control over node startup there is likely also a lot more unpredictability. Something like Knative can allow for faster startup times if you follow the common best-practices (pre-fetching images, etc.), but I'm not sure if it supports enough of the session-related feature that you were probably looking for to be a stand-in for Plane.
