As a non-'SAS user', I'm not a good person to respond to this, but
aren't you asking the wrong crowd? I have never come across this
concept in a proper statistics course, and in my very brief encounter
with it, it made absolutely no sense to me. But of course this does
not automatically mean that it's non-sense or anything. So rather than
asking R users who do not use it why they do not use something that
there is no obvious reason to use to begin with, why don't you ask
those who do (like whoever taught you to use them when you worked with
SAS) to explain why they do?
