Mostly realized this as I was about to put a translation label left of the data for it and thought about adding functionality to the template helpers so that we can use placeholders in the translation strings.

aka:

{{i18n Welcome "Name" $name}} can be use with Welcome = "Hello .Name" translations

but I wasn't sure how to prioritize because I was unsure about the layout supporting it or not.
