I do mean that, yes.

Well, HTTP has well-defined ways of indicating that a resource has 
moved.  HTML shouldn't be trying to take over from these established 
(and well-designed) divisions of labour within the system.

What's proposed is a system where people (or processes) are forced to 
edit the _contents_ of an object just because it has moved, whereas 
conceptually moving something around in a hierarchy doesn't necessarily 
require any modification of the object's contents at all.  I think I'd 
be correct to point out that such a situation wouldn't be very 
'RESTful'.

A URL can be opaque if you want, just as you can write nonsense HTML if 
you like, but if you want to take advantage of certain features of the 
Web then it had better not be.

Why introduce a new hierarchical system, when the URI/L specifications 
permit one that is actually implemented in all Web browsers already?

CMS systems that don't mesh well with the mechanisms already built into 
the Web are broken.  I'm well aware that includes many of them - but 
it's wrong to break (or simply over-engineer) HTML in order to find a 
solution!
