More random venting. What on earth is "wannabe portability"? Who knows what you mean by "nanny mode," but most people, including most pros, do use their laptops in ordinary ways for browsing, watching videos, text editing and other things for which the MBP gets excellent battery life. That's not eking out good battery life, it's just using the machine normally. Obviously that doesn't mean those people only use it for those things. They may also use it for more heavy-duty things.
A few more blows to this dead horse are just what's needed! The wider color, brighter--and higher-contrast--screen is something that can be achieved while preserving battery life and and other goals. Again, that's not true of 32 GB RAM, which would eat into battery life. Apple did, as a matter of plain fact, use the latest CPU. The dGPU was also the most advanced available that would fit with the other goals for the laptop.
The lack of repairability/upgradability is a real drawback, of course, but none of this has much to do with form factor, which is what you appear to be trying to talk about.
You can already fully use the power of these ports. Why do you suppose otherwise?
Again, a mix of myth, confusion about what was available last year, and pure nonsense about what "all" pros need.
No, not clear in the least. You believe what you want to, not what facts support.
