OMG! No! Having dealt with Go templates in the context of writing Helm charts, I would say this is not a a great idea. Please, invent a better templating language for Go, and then perhaps go down this path. That being said, I am not a great fan of templates in any language. Jinja2 might be a heck of a lot better than Go templates but it can still be hard to get right.

What is so wrong with this approach that makes you exclaim "OMG! No!"? This is practically no different to any basic server side rendering framework in any other language. This is a very basic pattern used all the time.
