iPhones are constantly bashed by a group of users because of not having USB-C connectors. Having four USB-C ports with identical capabilities on a MacBook pro is a more pragmatic and flexible solution to have, when compared to MagSafe.
On the power level and power button issue, Apple changes its features to shape customer behavior and expectation from its devices. Apple removed battery meter from Macs since it's standby is too long (30 days) and robust (auto-hibernation), so you're unlikely to run out of juice.
They also believe in the stability of MacOS such that it's not important whether the machine is off or in standby. Because it boots in ~10 seconds and wakes up in ~2. They want to remove these distinctions from their computers and try to lower your cognitive load. Actually this is one of the finest features of the Macs IMHO. They don't make you think to use it.
Open the lid, and if the screen doesn't come on, press the power button, done.
