PSRs are no mandatory requirements, not even a recommendation for general PHP development. They're just for frameworks to ensure some degree of interoperability.
Anyway, reasonable code style guidelines are always a good idea, so changes that improve the code style in this repository, ideally agreed upon before, are always welcome.
However, some rules, such as "4 spaces instead of tabs" will definitely not be implemented, as they're just a matter of taste and good arguments can be made in favor of both options.
