I add this task becouse :

task:
Add support for php 8.1
Not full resolve support for new version and was closed. because further work was in dependent tasks.

• FL-9463
• FL-9464

I presented the approach to this task in a private conversation with @semant, it seemed to me that I passed everything as understood, unfortunately the topic is dead.
Then I tried to mention these tasks on doscord unblock me, unfortunately no reaction in the above-mentioned tasks, I don't even know if they finally have a basis for such an implementation.

On bugs.funtoo there are problems related to it, for example:
FL-9614

In addition, I have tracked down new packages that unfortunately cause or will cause problems.

That's why I created this task which aims to provide packages that support php 7.4+ in order to reduce the amount of potential problems that can be reported by Funtoo users.

Privately:
reducing the number of local repositories I maintain for the purposes of maintaining the continuity of services, e.g. pecl-imagemagick

The task has also been created so as not to close the previous ones until a decision is made.
