Why not setting it directly on the pass it self? Yes; foreaching all passes to find any instance of CachePoolPass.

Otherwise maybe use a less generic name, to clarify something's going on (it's a tmp thingy, only to transfer config..), ie. setParameter(CachePoolPass::class.'_prefix_seed').

Guess to avoid creating params into the wild and making things less implicit. Im fine with it though.. just curious :)

This mix&matches framework.cache.prefix_seed and %cache.prefix.seed%, they're the same. In apps this often shows a code smell, as people tend to use params as some global config array, by exactly doing this.

$container->setAlias('cache.'.$name, Compiler\CachePoolPass::getServiceProvider($container, $config[$name]));
