It depends how it gets prioritized by the companies that own and contribute to these codebases - both open and private source. Right now there's not much incentive financially to migrate away from any of the existing code, so more often than not it will not happen. One reason why we're seeing stuff like the [FirecrackerVM](https://firecracker-microvm.github.io https://firecracker-microvm.github.io) or [AzureIoTEdge](https://github.com/Azure/iotedge https://github.com/Azure/iotedge) is that the companies behind them know they will attract privacy-/security-minded customers they might not otherwise have. There's other reasons as well, but this is just what stands out to me first.
