I am afraid you are not right.

Suppose you distribute BOTH Knuthian TeX and your own unTeX. You
decide to hack plain.tex to use with your unTeX. Fine with
Knuth. However, if this hacked version is picked up by TeX, you
violate the license. So you must take measures to prevent this. How
can you do this? There are two ways: either you remain plain.tex or
you put it outside the texmf tree. This is exactly what the current
LPPL requires.

AFAIK, LPPL was crafted (i) to spell out Knuthian ideas in a more
formal way and (ii) to weaken Knuthian requirements a bit, making
modifications easier. In other words, its authors tried to be
nice. As a result, you accuse them in making a license less free than
the Knuthian one. This is not fair, I think.

If you create non-LaTeX,  you can move files outside the tree, and
then you are completely free to do whatever you want.

Good luck
