Require twig/extra-bundle ?

[maximehuran]

Because when we require twig/extra-bundle we have this error :
Unable to register extension "Twig\Extra\Intl\IntlExtension" as it is already registered.

It is simple to correct by removing the line in config/packages/twig.yaml:

    Twig\Extra\Intl\IntlExtension: ~

But in context of Sylius Plugin it is complicated to say "Ok we will break your Sylius install, just change this file and it will be fine".

The issue could be solved by removing this line in YAML and add in composer json :

        "twig/extra-bundle": "^2.16|^3.12",

What do you think ?

Your solution works for Intl because the setup is simple :

But other extension needs runtime loader like this one :
