I actually spent a lot of time working on a response that explained the use-case. In doing so, it became pretty clear that it was fairly tightly coupled to our workflows and documentation style while likely not adding a lot (if any) value to most Geany users. So, I'll just close out the issue and thank you for your time.
Coincidentally, I drafted a page on the wiki that provides general information on templates; if someone would do a quick fact-check and let me know what corrections are needed, I would appreciate it.

Thanks!!
