Base images sometimes promise more than what we end up actually using. In analogy to --unsetenv and --unsetlabel, I'd very much welcome an option to unexpose a port from the final image.

My use-case: a Tomcat image exposes ports for the HTTP, HTTPS and AJP protocols, but I modify the configuration to only bind on the HTTP one (and leave HTTPS to a reverse proxy).

Seems reasonable, interested in opening a PR?

I would love to, but I don't speak Go. And I'm not having the time to learn it.
