As I said, the PSF license requires that derived works include a brief

preserving the PSF licence and copyright notice, is roughly all it requires.
There are no restrictions on the nature of changes derived works can make.

You asked whether it violated the license, not whether it was ugly.

It sounded ugly to me too, but the license doesn't forbid ugliness.
