Craig - it is my understanding, this is a very recent Canon development, and has only been initiated, so far - on the Rebel T7 and the Rebel SL3. However, more than likely, it will also be incorporated on any and all newer designs, coming down the Pike! … This, of course, is to force us to use ONLY Canon Speedlites. But, more than likely, it will be quite short-lived, as - Third-Party Flash Unit makers, will have a work-around!!!
Craig - it should be pointed out, here - the EOS 77D and the Rebel T7i - are, essentially - the same camera. The last generation - the T6i and the T6s - were also, pretty much the same camera (as each other) except the T6s - sported the top-deck mounted LCD screen. There were some other small refinements, but, apart - from those, the two were essentially identical. THIS generation - has now split into TWO categories - the Rebel T7i and the EOS 77D - again, the same pairing - but, the latter model - eschews the Rebel label. The Canon EOS Rebel T7, on the other hand - is a beginner camera (like the T6 and T5, before it.) THIS DSLR - is very different from the "i" series - which could be interpreted to mean - Intermediate, OR - "intelligent" as the "i" series Rebels, all sport (amongst other advanced features) the Intelligent Auto-Sensor Cleaning apparatus, which the straight beginner series, lacks. Therefore, the T7 is very different than both the T7i and the EOS 77D. Not only is the sensor slightly different, but the CPU is a much older design. Regardless, the T5, T6, and T7 - beginner Canon DSLRs - can be purchased several hundred dollars less than their "intelligent" counterparts, and because of this are very much more popular
