Over the years, several people have advocated the licensing and professionalization of computer specialists. There are benefits to this, but we should approach this idea with open eyes. Becoming a professional carries significant additional legal responsibilities that are enforced by malpractice liability. Therefore, we should not be subject to malpractice liability. A lawyer can make a persuasive argument that a CQE or CSQE should be subject to malpractice liability, even though we are not members of a recognized profession.
Engineering is a licensed profession, and engineers are subject to malpractice liability.
I became aware of the risk of malpractice liability in 1993 when my legal malpractice insurance carrier pointed out that my policy covered me for legal malpractice but not for engineering malpractice. That didn't bother me much because I generally like the idea of holding people accountable for incompetent work, whether they are members of a licensed profession or not. I continued to list my ASQC-CQE on my stationery since I received it, in 1992. If you are considering taking one of the ASQC exams, you might consider writing the ASQC and asking them to change the title on the certificate.
