Sorry for not conforming to the list standards, I am on my mobile.
Logins taking a long time is advantageous, remember we are not a
primitive/chatty protocol like HTTP; so burning CPU cycles during a
login is a VERY small problem; people often forget that we are not
in the same realm of HTTP. The advantage mentioned is that: more
time to verify a password = less brute operations per second = more
time for an admin to notice.
And so much easier to DOS a server without having to have an account
on it.
Really, advantageous all round.
