That makes sense. Most of the EE PEngs I know are designing electrical systems for data centers and other commercial facilities. Their stamp is the reason they have their job. Even in that sphere, most of the engineers are not PEs. But, there is still a PE role that is legally required before the design can be implemented.
If we are talking about electronics, then yes, the current reality is that EE stamps are generally not needed in the legal sense. This thing I wrote is a first step in imagining what sort of world would exist if electronics and software engineering had a legally-required PE level.
