Why do you need "actual modules"? I feel that (when PSR-4 is followed) PHP's code separation practices are among the best, especially compared to other interpreted web-languages (Python, Ruby, js). And it's convenient while experimenting that it doesn't really enforce anything.

Without modules there can be dependency hell: conflicting subdependency versions, unless all your dependencies update their subdependencies in lockstep.
