Implicit dependency twig/twig

[underground20]

Q	A
Bundle version	6.10.0
Symfony version	8.0
PHP version	8.4

Support Question

I used Symfony 7.3 and bundle 6.9 version. After upgrade Symfony to 8 and bundle to 6.10 an error appeared "Service id "Knp\Bundle\PaginatorBundle\Twig\Extension\PaginationRuntime" looks like a FQCN but no corresponding class or interface exists. To resolve this ambiguity, please rename this service to a non-FQCN (e.g. using dots), or create the missing class or interface."

This probably happened because of this change "Registering a service without a class when its id is a non-existing FQCN throws an error" in "symfony/dependency-injection".
Bundle does not require "twig/twig" like explicit dependency. Is it a bug?

No, it's a design choice: you can use the paginator without templates, so Twig was too heavy a dependency.
The README states clearly (in the "Requirements" part) that if you must require it, if you need it. Note that you'll likely also need to require the translation component.
