It strongly depends on the person. If you get enough sleep and you have high testosterone, you can pretty much train every day. Your advice does hold true for most of the population though.
You seem to assume that people are looking to learn and grow their computer abilities. Learning takes an open mind, which isn't the case for most people.
Ease of use enables the user to perform actions with more impact. Think of it as Python vs C. You need a lot more knowledge to get started with C, but you can customize almost every aspect of your program. With Python, you lose some customizability, but you can do a lot more in a lot less time and understanding. If you need the customization and you have the knowledge, you can also build C extensions for Python (which would correspond to the chrome flags).
I'm not saying I'm for this change or not. Testing it out on real users will decide its fate, I'm quite ambivalent about it. I'm just speaking for ease of use in general.
