Macro-less User Language Files

Are there any plans to integrate key based user defined language files into the scripting language that do not rely on messy macros?

Example nsi script
==================

LoadLanguageFile "${NSISDIR}\languages\English.nsh"

LicenseText $(Agreement)

Contents of English.nlf
=======================

!define Agreement "You must agree to this licence before installing."

No, there are no such plans.
