thanks for explanations.

I think the crucial sentence in draft3 of GPLv3 is (section 6):

"The information must suffice to ensure that the continued functioning
of the modified object code is in no case prevented or interfered with
solely because modification has been made."

I have now read it multiple times and i think it will probably achieve the
same like this sentence (from section 1draft 2):

"...such that they can implement all the same functionality in the same
range of circumstances. (For instance, if the work is a DVD player and
can play certain DVDs, it must be possible for modified versions to play
those DVDs..."

But i think the language in draft 2 was straighter and more obvious.
