Someone please correct me if I am wrong but I believe the answer is yes. I believe this is the relevant PR:

https://github.com/elm-lang/core/pull/25

I believe the original improvements were done here: https://github.com/jwmerrill/elm-animation-frame

I modified a game I wrote to use the modified run time. I can see a huge difference between the two in Firefox.
