In 4 years time when the peripherals have caught up we can start phasing out older ports and go full USB-C.
But you see, that's what makes the old ports hang around forever.
I'm sorry; but USB-C/TB3 really
is "One Port To Rule Them All". And no, I have never said that about any other Port. We have one Port that instantly replaces USB-A 1.0 thru 3.1 (USB-C), Ethernet, MiniDP (and therefore HDMI/DVI/VGA as well), FW800, and ThunderBolt 3. And can even do a lot of that
Simultaneously.
Times FOUR. And all that for the price of a a couple of adapters (NOT a "bag-full"); most of them readily available from a plethora of manufacturers (
not just Apple), for $3 - $20 (and by the time we get to $20, it is generally a multi-port "dock").
Here's one for $8.88 with 2 USB 3.0 Ports, A bunch of Card Reader Slots, and a USB-C Port:

Here's another mini-dock that sports 3 USB 3.0 Ports and a Gigabit Ethernet port for $20:

Here's another for $23 that has a USB 3.0 Port and a 4k-capable HDMI Port, and a USB-C Port:

Here's another one for $24 that has 4 USB 3.0 Ports, a VGA Port, and a USB-C Port:
https://www.amazon.com/AUKEY-Charging-MacBook-ChromeBook-Devices/dp/B01ESWAVKE/
...and if you're willing to go a little higher, here's a $40 dock that has 4k HDMI, 1080p VGA, and USB-C:

And $43 gets you pretty much everything in one little mini-dock: USB 3.0, 4k HDMI, 10/100/1000 Ethernet, and USB-C:

...Add a buck to that, and you can have a VGA Port, too (either HDMI or VGA can be used at a time):

And I don't know about you; but I WELCOME not having a bunch of connectors dragging my laptop around, making me feel like I dare not bump it on the desk at home, lest I yank-out a cable. In fact, I would add a nice USB-C Extender cable to any of those, so I could keep the laptop "free" of a bunch of cables directly plugged into it. Here's one for $6 that would be just about right for the desktop:

Now consider this: If you use a Laptop, you are already traveling with an AC Adapter. Period.
If you have pretty-much ANY Laptop built in the past couple of years it WILL have MiniDP video out; therefore, you WILL be using an Adapter with an external Display (this is why you can buy those adapters a Walmart now).
So, now we have TWO adapters that EVERYONE is carrying.
And, as seen above, if you do a little shopping-around, you can cover pretty much everything you need in one or two other "mini-docks",
not a zillion separate adapters!
And the "mini-dock" selection is only going to get better, as more and more laptops switch to USB-C/TB3 like THESE already have. Note that MOST of those on the list are NOT Apple. They just jumped in with both feet, creating a laptop with more I/O capability than anyone else on the planet. Look for others to follow almost immediately:

Now, let's talk MagSafe: I wholeheartedly agree that MagSafe was wonderful, and I hope Apple figures out a way to bring it back. But for now, at least we have this Griffin replacement. It's a bit pricey (but much less than a laptop repair!), and it has a few issues; but here you go:

Oh, and you mentioned valuing "Flexibility". You should realize by now that with the plethora of available adapters and mini-docks, you can turn
every single port on the 2016 MBP into
exactly what suits YOUR needs at the time! Apple DID make a Laptop JUST FOR YOU!!!!
So, sorry, you lose.
