In contrast, another put it down to the fact that important software/frameworks did not support PHP 8 until recently. I think… continue reading.

No this is not the main reason. The process of upgrading the PHP version is an engineering investment that virtually doesn’t pay off but a risk management. The whole process of converting or porting the codebase, setting up new environments, testing it, etc. is NOT cheap and it doesn’t change anything to the end-user nor the clients using the served website. Basically, there is no time for this.

Knowing that, I think PHP historically did a great job of minimizing compatibility issues between PHP versions, especially between minor versions. But going to PHP 8.x from 7.x comes with a set of now removed deprecated features and a new set of deprecations.

Anyway, case in point, the ratio of cost vs gain here is completely in the RED.
