I think you're thinking about this too hard, or maybe I wasn't explicit enough. Typing from a phone causes that.
Yes, I'm staying if you are building the type of network where you have identified a large MTU is desirable on the L2 path, you want everything to be as high as possible, and you will be limited by the devices smallest MTU on the path.
