A few weeks ago people were discussing here how their typing speed was making them code faster. On the other hand I haven't been limited by writing code, the linked article match my professional experience.
Speed is part of fluency and almost a shortcut to explaining the goal in real terms. Nobody is hunting and pecking at 80wpm.
The fact is that programming is not about typing lines of code into an editor
Improving typing speed from "fast" to "faster" is very difficult. I think it's worth distinguishing between "typing faster is not useful" and "it's not worth the effort to try to type much faster".
There are sometimes cases where it's worth paying a high cost even for some marginal benefit.
