We turn it off by default because its a rather large dangerous security
hole to leave around when a naiive user makes a basic installation. It is much
better that it is enabled by someone who knows what they are doing and makes
the decision to do so. Thats why we contributed the patch to make syrq runtime
configurable

Tools like powertweak even give you a nice gui interface for managing it.
