I share the same perspective. For what it is worth, not too long ago I came across the concept of “portable monitors”. Took a risk on a 4K 15” model and it ended up being decent quality. Skinnier than a #2 pencil and perfect size when propped next to my 15” MBP, without getting in the way. edit: Almost forgot to mention this — it is powered via USB-C cable. One end to the monitor and the other into my 15” MBP (13” MBP may not have enough “juice” to power).
