This is not a good trend

> To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.

In other words: If you distribute any file that is not 100% identical to a file provided by upstream, then you have modified the work.

You can scream until you're blue in the face that this is inconvenient, unreasonable, not what people do in practice, overly strict, etc., but if you get sued, the courts will not be interested in anything outside of the four corners of the license as it is actually written. So you should comply with the license as it is written, or at least be prepared to comply when some upstream inevitably asks you to do so.
