But sshd can be moved without problem. Moving httpd or worse, sendmail
would break things.
Also, I dont think anyone here would suggest that this is a replacement of
other good security practices, such as those you mention, only something to
add to if you wish.

Just because they are good, does not mean they dont make mistakes.

The point here is, there are not ill effects from moving it, and possibly,
in some cases actually prevent a break in.
It might not be necessary for 99.99% of the time but if it saves you once,
then its paid for itself.
