Unexpected behavior

License, authors are required, if not included in the composer.json the extension is skipped.

I expected that this would work
{
    "name": "thecanyons/homecontent",
    "type": "phpbb-extension",
    "description": "Strict minimal phpBB 3.3.15 compatible extension",
    "version": "1.0.0",
    "extra": {
        "display-name": "Home Content Official Minimal",
        "soft-require":

{             "phpbb/phpbb": ">=3.3.0"         }

    }
}

This works, so there must be some requirements for the extension that are now with composer 2.5+

Documentation needs to be updated.
