In fact, 'rm -f a a' still does twice the filesystem operations.
It still calls newfstatat(AT_FDCWD, "a", ...) twice and unlinkat(AT_FDCWD, "a",
0) twice, on my system.
What I am suggesting is to check for the same filename string having been seen
before and avoid touching the filesystem.
This is a small user-friendliness improvement in the mode without -f, since
"warning: file 'a' specified twice" is easier to understand
than "cannot remove 'a': No such file or directory", but it is also a
performance improvement.
Pretty marginal I admit, except perhaps for a network filesystem hosted by a
server on the other side of the planet.
If you say "rm a a", you get what you asked for.
You wanted to remove "a" twice, and this normally doesn't work.
I don't see a reason for a change.
