Agree totally.

What Fantasai is asking is if it would be better to have the same order that each multiple text shadow is called as each multiple background image is called in comma separated strings like:

div {
  background: url(a.png) 0 0%, url(b.png) 100% 0, url(c.png) 100% 100%; /* top to bottom */
  text-shadow: 10px 10px 0 red,  19px 90px 0 blue,  100px 60px 0 yellow; /* top to bottom */
}


An author would find it easier (and more intuitive) to change text-shadow "red" and background "url(a.png)" since they both would occur first. In the specs for multiple backgrounds we have "The first image in the list is the layer closest to the user, the next one is painted behind the first." Text shadow should have the same order.
