I agree partially, I'd say speedruning easy is easier now, but times are still generally slower because brute has a longer death animation than grave digger, which causes wave 25 to be about 3-4 seconds slower.

Thinking that would be done since their hiding official proof that they did the run

I timed grave digger's death animation before brute was added to be 6 seconds, and brute's death animation to be 10 seconds, so to keep older runs up to date, they should have 4 seconds added.

Good one

I already knew there could be time improvement with grave digger
