So yes, changing the ports isn't ideal and only having one to use to plug in peripherals which will most likely mean a hub is required is a bit of a pain, but the low end doesn't even include the touch bar so I'm not sure what you're getting upset about?
Plus, the current generation of Macbook Pros weren't expandible as far as I'm aware? I've got the 15" rMBP and I can't upgrade anything within it, so I doubt Apple is too concerned anymore about allowing expansion in their laptops and I could see that trend spreading across the rest of the industry as well.
