I am happy to report that this idea was reviewed and accepted for development. I will update this ticket again when this functionality has development started and a release date is clear.
Thank you for your idea.

This seems like an ask for the ability to perform a workaround for what you are hoping is a performance increase. If so, I believe the better ask is to simply have Windward investigate doing this task on generation -- look at the tags, trim the content of the xml that isn't referenced by the template, and see if that improves performance.
