Philosophically: L'État, c'est moi, build your crappy cgi scripts with nginx or apache all from the CLI and all in vim and you will understand.

Practically: Ports 22, 80, and 443 open and directly accessible from 0.0.0.0/0 is extremely manageable.

Why would anyone today leave port 80 open? I do https by default even for my blog.

For me personally it's just old configs I have that redirect from port 80 to 443. You're right though - probably unnecessary in this day and age.
