There was a problem hiding this comment.
This is a recurring question, see #19504
The consensus is that opening port should be a deliberate admin decision and we don't want to do it automatically. Plus you may want to make a service reachable only on some interfaces but not all.
sshd is actually the exception here, not the model. :) It's here to avoid users locking themselves out too easily.
And even if a module provides a convenience option for the default NixOS firewall, the default should be false and not true.
Maybe a simpler approach is to just mention the prerequisite in the description of the module port option.
BTW adding yourselves to maintainers-list should be a separate commit. :)

Motivation for this change
This was inspired by the openssh service, and others, which have the openFirewall option to open the port that the service uses. When enabling the service, one would expect it to work and opening firewalls is often necessary for this. As openssh has openFirewall enabled by default, I choose to do this as well.
