Not on the final directory component.
But on any others, it is.

No.  To demonstrate this, you have to create a nontrivial hierarchy:

  $ uname -r
  5.9
  $ mkdir y
  $ cd y
  $ chmod g+ws .
  $ /usr/sbin/install -d -m 0755 a/b
  directory a/b created
  $ ls -dgo a a/b
  drwxr-sr-x 3 175 Dec 16 23:45 a/
  drwxr-xr-x 2 117 Dec 16 23:45 a/b/
  $

But your point is valid.
Changing the permissions on the final component does make more sense.
You're welcome to do that.
