There are a decent number of nodes that are present in ipv4, ipv4-raw, ipv6, ipv6-raw, and bridge. These can all be added to a common-rule-all.xml.i file, which will make new features that hit all of those files easier to add.

For instance, https://vyos.dev/T8221 could have had a single touchpoint for applying the node, instead of being applied to five different files.
