When do we drop PHP 8.0 support?

https://packagist.org/packages/codeignit.../php-stats

1. It seems to me that this is not relevant data.
This graph shows package installations. That is, if I install the package ten times through the composer, and then delete it, it will count as ten installations, and not one in fact.
Since CI supports several PHP versions, you can change the version without reinstalling the framework.

2. There are no statistics on the use of the zip installation.

It makes no sense to abandon only php 8.0, leaving php 7.4.
And according to the given statistics, then 7.4 + 8.0 = 43% (for 4.3.*)
