I haven't put /proc explicitly on my /etc/fstab since a long time ago, and everything seems to be working. However, I use systemd, which always mounts /proc with the default options, and only uses the entry in /etc/fstab (if present) to override the default options. In other words, systemd always mounts /proc, no matter if it's listed in /etc/fstab or not. I don't know what OpenRC does, but it would not surprise me that it's something similar.
