PHPStan & CS-Fixer Rules for Plugin Compatibility Across Shopware Versions

[pavel-rossinsky]

The PHPStan job for a Shopware plugin or app requires a configuration file. I am developing a plugin or app intended to be compatible with Shopware versions 6.4.* through the latest release.

Are there specific sets of mandatory PHPStan rules that my plugin must adhere to for each Shopware version? For example, should I use version-specific config files like 6.4-phpstan.neon.dist for Shopware 6.4.*?

Additionally, does the same principle apply to the configuration of PHP CS Fixer? Are there distinct mandatory rules for code style compliance per Shopware version?

Thanks in advance for your help!
