The 'filter' property takes, as its original input, the element
itself.  The filter() function instead takes the passed image as the
original input.

Using filter() instead of 'filter' would require some way to refer to
the element itself as an image (not necessarily a blocker - we already
have element() which does basically this), and some probably-confusing
interaction with 'content', like:

.blur-me {
  content: filter(contents, blur(5px));

Animating filters would then require that 'content' itself be
animatable, which may or may not be weird.
