Blah. That's just your own made-up explanation of what you think "const"
should mean. It has no logical background or any basis in the C language.

"const" has nothing to do with "logical state". It has one meaning, and
one meaning only: the compiler should complain if that particular type is
used to do a write access.

It says nothing at all about the "logical state of the object". It cannot,
since a single object can - and does - have multiple pointers to it.

So your standpoint not only has no relevant background to it, it's also
not even logically consistent.
