...SD cards, arguably the slowest and least reliable available option, are the logical thing to leave out.
Features have been disappearing pretty much in size order, with"enormous" disc drives going first, followed by "too fat" ethernet ports, and logically followed by SD card readers.
And that's it! We're down to 4 USB C ports with the only remaining option being two USB C ports and a hub.
More: Thanks for linking to the card reader thingy you use. I wasn't aware that such a thing existed.
