What is more effective? To add support for PHP 8.2 and above, or to move thousands of projects to CodeIgniter 4? And which one is realistic to achieve? ;-)
Why to abandon a lot of good projects just because PHP changed? I have few of them and I will not upgrade them to CI4, but I am willing to update them to be compatible with new PHP, because I putted a lot of effort to them and wish to see them live.
If this compatibility issue of CodeIgniter 3 and PHP 8.2 and above will be successfully solved, than we will have thousands of projects thriving for years, I think. So what are the problems? Maintainers? Incompatible design of CI3?
