@Pete-S said in Debian 11 & php8:

Not a challenge at all but the reason to run "stable" is for stability.

Once you start abandoning the integration, though, you are abandoning stability. The idea of using an LTS and then replacing the parts of the OS that aren't up to date is counterproductive. Choose the most up to date, best supported, most stable version and use the fully tested and integrated components instead.

The idea of "stable" is not stability in IT terms, that's a myth. It's actually against that. The idea of current is for IT stability. Stable, in reference to an OS like this, is in reference to the versions of products remaining stable so that unsupported, out of date software from bad vendors can be used without updating for long periods of time. Not a positive stable, it's a bad stable.
