I quite agree that it's important to actively seek out and work with template creators and curators to get involved in testing out Lua. But it is also critical to involve those who will be *using* the templates to see if what has been designed will address any or all of their concerns and issues. Making the wiki run faster is, I believe, only one objective in improving the "template experience". If the product that comes out of Lua is as difficult to use as the current templates, then we have only completed half the job. (I use "we" as the big-tent community that includes developers and editors.)
As far as I know, this doesn't really change the template experience from a normal editor's point of view.
