Thanks for the update @standpoint
There has been many attempts do this over the years but non had enough strength to pull through.
I'm thinking about creating a new initiative, raise awareness and gather enough support to tackle this complicated issue.
Symfony supports runtime, which might be a good start. It's suppose to support different runtimes for running symfony
https://symfony.com/doc/current/components/runtime.html
As for static variables. it is possible to workaround it. There are multiple ways to address it. it appears that Swoole can handle it using co-routines

I don't think enough people are aware of the massive performance boost effect this feature can Drupal!! otherwise it would be done long time ago
You're both added, happy contribution guys
