Well, as it worked this way every since there has been POV-Ray, how can it
be a bug?  Simply trying it out in 3.1 or earlier could have answered the
question.  And you surely have used 3.1 before so you know it worked its way
there.

Apart from that, nowhere in your original post you suggest it is a bug, and
no matter how often I read it, even between the lines I can't find a bug
report in there.  Your post doesn't sound very "polished" either, which it
should have been if you had seriously discussed it before elsewhere.  Of
course explaining complex ideas can be difficult, but trying to think about
them more would be a good idea.

I see.  Indeed, this would not require to store the whole image.  However,
as it hasn't been needed in 15 years and I don't remember a patch for it or
any suggestion for such a patch.  I really wonder why it would be an feature
so important it has to be added to 3.5 (so to post here), if it would be a
worthwhile feature in the first place is yet another question, but I don't
want to get into a discussion about new features at all...

Few people created off-topic threads, most of the time it developed
throughout a thread.  Saying you post here because "I've discussed color
clipping in the other groups before but never really got a clear answer on
what I really wanted to know" surely doesn't sound a justification to me,
only like a way to force some answer, which you got.

As for my reminder, it was not personal and wasn't written this way either,
it was a reminder about the rules we have set up in these groups and try to
hold up.  That occasionally this doesn't work is hardly a justification for
ignoring the rules :-)
