Hello @chrismask,
Thank you for contacting Rank Math support.
rank_math_robots key is only generated when you set the robots tag manually for a post. If you use the default value from the global settings, then the key will not be there. So our implementation is already focused on avoiding unnecessary generation of meta keys and only adding them when they are needed.
Hope this clarifies your doubts. Please don’t hesitate to get in touch in case you need our assistance with anything else.
