There was a problem hiding this comment.
Personally, I'd prefer something like this, with more verbosity provided for invalid configuration values.
$serializerClass "normalization" could be extracted to a separate private method. Similarly, exception message/instance creation.
Also, added check that the instance we are creating is actually of the right class. Usually object creation is a domain of an app, but in rare circumstance that somehow user could control what ends up in $config['serializer'], a malicious user could for example create PHP subprocesses that would allow backdoor access to a server. Unlikely, but it doesn't hurt to check.
