Optimized key management to avoid duplication

[roukmoute]

Hello Symfony Flex team,

I'm writing to ask you about a technical detail I've noticed when using Symfony Flex. When I use existing keys, as in the Makefile, it seems to create duplicates. For example, I've defined my own "help" rule and this creates a duplicate for me.

Similarly, with the docker-compose (and docker-compose-override), when I want to change the default key of an existing key, because of my personal recipe server, it seems to generate duplicate keys.

Is it possible to set up key management for each environment variable or rule in a Makefile? This could greatly optimize the experience of users like me and guarantee greater flexibility in configuration.

Thank you in advance for your attention to this proposed improvement.

Best regards,
