Well, at least "at" is a nice command and some people use it, but…

… it's time we drop such legacy junk! Scripts are all written to sed (or 
something entirely different, like awk or perl) these days, and nobody 
seriously uses ed for interactive editing (there are tons of more usable 
text editors around). Sure, we can keep "ed" in the repository, but I don't 
see why we install it by default.
