First emacs is still a rather small executable, there are much larger ones around.

That large xattrs tend to be out of line on a separate block and that would cost an additional seek. It would be unlikely to be continuous to the rest of the file data and thus even be worse than the SHDR which is at least likely to be served from the same track buffer as the executable.
