While I understand that the Janitors decide if the node should be modified based on a consideration, the documentation at How do I use the power of consideration responsibly? states under Good reasons to consider a node include:

To fix formatting, e.g. adding <code> tags around code, adding <readmore> tags.

The long standing trend is not as documented, so which is policy? The documentation linked from the top of the Nodes to Consider page, or many conversation nodes that may or may not have been read, or perhaps, remembered. Would it make sense to update the documentation for consideration to reflect current site policy and remove that conflict? Even a small change to the document, such as "s/tags\./tags for the Anonymous Monk./" or some such limitation would make it clear that this is not the SOP for moderation. As it stands, the documentation is contrary your stated site policy.
