They are not allowed while reading in the middle of a regular file,

Weren't GNU programs supposed to be free from such limitations[1]? For example GNU ddrescue will accept any number of short reads anywhere in the input file.

"The GNU Project regards standards published by other organizations as suggestions, not orders. We consider those standards, but we do not "obey" them. In developing a GNU program, you should implement an outside standard's specifications when that makes the GNU system better overall in an objective sense. When it doesn't, you shouldn't."
