I knew defining a dongle would bring out the pedants, and that makes me very happy, but I think the real point is being overlooked here.

Folks who want an SD card reader or HDMI should carry around SD card readers and HDMI cables. People who don't want those things shouldn't have to carry them around.

I modernized all my accessories years ago. USB-C is all I or, I would argue, nearly anyone needs. I'm truly sorry that your job requires you to carry a little extra gear, but it's not my job, so don't burden me with it. (If you disagree, then explain why the MBP shouldn't have compact flash, micro SD, etc.)
