They haven't been expanded for years, if ever. You have broken any user
of the unexpanded variables already. ${var} is a pretty intuitive
semantics for "show me this expression". It even works for complex
expressions involving modifiers. Your change has increased the
complexity of the argument format without providing any new value. It
has broken compatibility. It was not discussed. I think those are more
than enough reasons to ask for a revert.
