I understand your point, but my experience is the opposite. On my old MBP, I'd be using nearly every port when docked at the desk. My 2016 MBPwT has only four connections which means that at power+GbE+DP+mouse&keyboard I'm now out of ports for anything else. My only option is spend even more money on a docking station which has its own share of problems (I've been searching for a decent one forever).
It wouldn't be so bad if it wasn't for the fact that USB-C/TB3 has been such a disaster and even mechanically a disappointment.
I was stoked before getting my Dell Precision 5510 (aka XPS 15 Pro) that it would have a USB-C docking station. It would be awesome with one tiny cable for power+displays+all my desktop USB devices.
But it's never actually worked, I ended up RMAing the docking station. Since the laptop itself can only support one display, I can't have dual monitors. So now I have a 43" 4K monitor, a USB hub and a power connector that I need to plug in/out all the time. And Win10 still gets confused about DPIs and scaling and stuff.
On my ancient-but-still-kicking Dell Precision, at least the docking station actually works and you can simply click in and out in three seconds.
