That’s not a bad idea, but for now you could use and modify this plugin I made for a StackExchange user to access Template metadata within a template.
We already have {template_edit_date}. {template_id} and {template_group_id} could complete the team and make the debug easier. Together with something telling us if the page is being cached.
Sometimes, the template debugging log is too much, @Derek. Sometimes, something like this is enough.
Thanks for the attention, @Derek!
