Thread:User talk:CodeCat/Category:term cleanup/with sc/reply

That category contains pages that use with no language but with a script. So it's not quite what you had in mind. I suppose adding a script when a language is already specified does speed things up slightly, but that is only really recommended in the short term. Once a template is converted to Lua, it will not make a difference anymore. So I really recommend just not doing it, to avoid (possibly confusing) redundancy if nothing else, and also since it's only a short term improvement.
