👎 on my side, that's way too specific. I mentioned an approach that could work insymfony/recipes#1314 (comment), but we first need to be sure this needs to be improved. At the moment, the env var is needed only when activating one of the features listed in my comment there. A better place to tell about the feature could be in the documentation of those features.
Note thatfile_put_contents(".env", [...]) is putting a secret in a committed file. No-go :)

thx for stopping here and commenting
indeed.env.local is more appropriate 😬

for the doc part, I tend to agree as well even if now I dont know were to document this specific use case
lets wait other ideas thanks :)

Closing as this approach is not the one we'll want to merge.
Thanks fur submitting.
