It is not a question. It is an illustration of grades
of implementation dependency.

Remember you promised to rephrase the original question.
What is wrong with the OP is not just about differences
in terminology or coming from another place; it is more
basic. There are (some underlying, some obvious) assumptions
which are false. When these were brought to your attention
earlier, and in this thread, you said you understand.

Sometimes you do, but sometimes - as soon as in the next post -
you get back to the same, false assumption.
Your IMO wrong understanding of the role of links is
amazingly persistent. Please take your week
to try to crunch it, and show that you did later on.
