Why didn't we go with the option of adding the argument to the existing interface, with a proper BC layer? It would make sense to me, don't you think so?

Replacing the concrete method by a virtual one until 6.0? Our BC promise needs a patch :)

@chalasr no need: just adding an@param annotation is enough, alongside with:

• a commented argument on the signature,
• all implementations updated accordingly (in a similar way for non-final/internal classes)
• notes in UPGRADE-5.1/6.0.md + CHANGELOG

@Braxilior up to do it ?

yes 👍

@chalasr i do think the BC promise needs a patch in general. Seesymfony/symfony-docs#10504 for reference :)

Thank you@Braxilior.
