Might not be much of a difference in a simple configuration, but going
up and down dirs is not free even on a fast SSD, especially as the
number of the elements on this hook grows.
But where you will definitely see a difference, is when using this with
Tramp.
Have you seen the code I posted? You'll notice that it doesn't do
any file system operations, it just does file name operations. And
those run in CPU/memory, not file system. So I cannot understand
your argument. But I am happy to measure performance in different
scenarios, if you'd like to suggest a particularly problematic one.
