This sounds like you don’t have much exposure to actual professional engineering disciplines. I’m sure civil, electrical, structural and mechanical PEs would be quite surprised to hear there are no guardrails on their professions.

Engineers versus "engineers".

I have fond memories of a boss who was an actual, licensed engineer while the rest of us were very much normal software devs. Boss was pretty chill except when someone someone suggested we should be called "engineers" rather than "developers", at which point they said "if you guys were building bridges, people would be dead." (I don't think all software needs to be built to rigorous engineering standards but man... I think about that line a lot.)

In my experience “engineers” and builders are often quite “conservative” and really don’t like pushing the envelope, and they often only do it under protest.

The most famous example may be the perpetual war between architects and engineers/builders.

I actually originally wrote "technologists" but thought that the word sounded kind of odd. Now I realize it better captures what I was trying to convey.
