I think we need to define this for all other Symfony Runtimes also or is frankenphp the only when where the autodection does not work? If we need define it for all Symfony runtimes, does somebody has the correct insides what the correct values for specific runtimes are?

If example Roadrunner does web requests but little bit different as FrankenPHP as it runs PHP from Roadrunner GO Server via CLI context as I know. Would it be still the 'web=1&worker=1' or would it be in that case 'web=0&worker=1'?

PS: Psalm & Composer normalized are fixed on main.

This must be done for all runtimes but I'm not sure of the value to use for web. It should probably be set to 1 everywhere is errors are generated as HTML. cc @nicolas-grekas
