Yea closest I see to being better about it is Frame.work laptops, and even then it's not as good a story as desktops, just the best story for upgrading a laptop right now. Other than that buying one and making sure you have at least two thunderbolt (or compatible) ports on separate busses is probably the best you can do since that'd mean two 40Gb/s links for expansion even if it's not portable, but would let you get things like 10GbE adapters or fast external storage and such without compromising too much on capability.
