Hey @Wbm1058, I mreged your latest entry into the one above it, because "structured" means something specific and technical that isn't actually present in the example you gave. If a discussion is "structured" to use that template, then you would have no choice about whether or not to use that template. A structured process for requesting a page move would be look more like a form that you filled out. Instead, what we use is a blank section with no imposed structure.
I particularly want to thank you for posting that very interesting example. I think that it's important to remember that "free-form, used freely" is often not what editors actually want. What enwiki's WP:RM is using right now is technically "free-form, used in a specific way" – ike a typist from the 1960s who always typed three blank lines between the date and the address on a business letter: there's a conventional approach, but there's nothing actually stopping her from typing a letter however she wanted to on that blank page. It would be interesting to build something that changes that fully to a structured system.
