@xarem just as PHP 7.4 had many not-ready extensions and some deps were not really prepared for alpine, I just released (back then) the stable without some features (xdebug being one of them).

We can strip out pear on the build process ( but leaving a multi-line @ TODO so we remember to check and add support afterwards)

The earliest we get a minimal feature 8.0 running, the easier will be to solve the pending incompatible things.

I may use this as starting point and dig this a bit within the next days, but feel free to keep on this if you wish, just take in mind the first drafts and alphas and RC's almost never got feature-full on the first builds, it was after PHP 7.4 was long stable that xdebug catched up, and honestly, I do not use PEAR, so I would not even miss it immediately

Changed this to branch feature/php-8.0 so we can improve and work locally on the repo, gonna merge so we have the WIP branch, cool?
