Sure, but my main point was about having "Provides" be a multi-valued field,
which opens the door to a lot of complexity for perhaps little or no benefit. I
don't have any problem with the use of "Provides" as a canonical name for a
distribution. Even before Pillow came along, there used to be confusion, IIRC,
between the names "Imaging" and "PIL".
