First of all, there is no objective right or wrong. What you think is wrong
might be right to me, and possibly a lot of other users.

So clip it at the maximum value that the output format supports? Which
happens still to be 1.0 at the vast majority of supported formats.

Not arbitrary.

And I suppose that this thing that you call a trick, and which many users
want, and which make many images look better is *wrong*? Why?

And when I define the problem as the presence of jagged edges, then why is
the discussed clipping not a solution to this problem, when it does indeed
remove the jagged edges?

Mind you, for me a "solution" is to use POV-Ray 3.5 instead of 3.6. It's
just not a very good solution. You can't say what's a solution and what
isn't to a problem that I have defined.
