It's not at all useless.  Dired offers many features,
including many that many or most users never use or
are even unaware of.

There are, for examples keys to navigate among dir
listings, that specifically move to dir headlines.
`C-M-n', `C-M-p', `C-M-d', `C-M-u'.  Not to mention
`i', which inserts the listing for the subdir on the
current line.  (And in Dired+ `i' on a subdir listing
takes you back to the parent dir listing.)

It may make sense for you, but it doesn't necessarily
make more sense for other Dired users or Emacs in
general.  Luckily for you, you can bind keys to any
commands you like:
