OK, it's useful and amusing. But...
Reasons why the Win7/Vista/Win8 'God Mode' sucks
1. That it's even necessary. Why _isn't_ there a default single convenient 'place' where all Windows controls are located? Not to mention, why isn't there a way to save/load _all_ the Windows config settings in one user-editable file?
(Answer: Because then Microsoft wouldn't make as much money from their 'Microsoft certified systems engineer' courses. Microsoft prefers to keep Windows mysterious and difficult.)
2. It adds another special case to the file system. "It's not a folder as we know it, Jim!" Special cases are bad. Add too many of them and system complexity tends to go exponential due to the inevitable interactions. Just like it has in Windows.
3. So, Windows implements programmatic execution of folder names? Within pathnames? That's truly evil. It's a security breach time bomb waiting to happen. Or more probably, deliberately put in place for an intended later use. Aka backdoor. Or demolition charge.
4. Yet another reason why Windows is _slow_. With every pathname it processes, it has to always check to see if it contains a valid CLSID number? To do which it has to scan a large part of the Registry! This is as bad as the WFP (Windows File Protection) scheme, which requires that every file modification call has to be checked against the list of thousands of names of system files that are not permitted to be altered.
5. Another crazy abstraction. What was wrong with having an executable, a utility, to produce a control panel-like facility? Instead of abstracting the feature to magically appear in a filesystem place? Oh but then it wouldn't be...
6. HIDDEN. It's an easter egg, a hidden, undocumented feature. Since it's remained secret for so long (since Vista was released) it has to have been put in by some small group in the Microsoft software teams. It may or may not have been approved by management. This is evil too.
7. But most evil of all - it _proves_ (yet again) there can be _and_are_ major hidden functionalities in Windows. That persist across major version changes. What _else_ is in there that we don't know about?
This once again demonstrates that Windows as an operating system simply cannot be trusted.
