I feel that the whole issue is turned the wrong way. The LAE is licenced to practice - you need a licence to be allowed to issue a CRS. If you issue a CRS without holding a licence, there are crinminal sanctions. EASA and the FAA can call such people technicians or mechanics as they wish, but the ICAO refers to "Engineer's" Licences.
If the engineering profession wishes to protect the status of engineers, then graduate engineers in general should also need a licence or registration to practice engineering. If you hold yourself out to be an engineer when you aren't licenced or registered, there should be legal sanctions.
As an example, you can take a law degree, do the post-graduate course at The School of Law and pass their exams, but you can't practice as a solicitor unless and until you have been "admitted". Solicitors must renew their practicing certificates annually by proving they have practiced as a solicitor during the past 12 months. In UK you can take a medical degree and do the post-graduate training, but you can't practice as a Doctor of Medicine unless and until you are registered by the BMA and have a current certificate...
...and so on. In "The Professions" you must have the basic educational and professional qualifications and then be registered and/or certified in order to practice. Get yourself "struck-off" or let your registration lapse and you'll have to find another career.
The general public understands quite well what constitutes a Solicitor, Doctor, Dentist, Accountant, Psychologist and the like. The problem is that just anybody can call themselves an Engineer - and they often do!
