See bug 932418 for an example of how this can screw us. We should abort in debug builds and warn something to the error console in opt builds if you pass a non-null argument as aPrompt.
I wonder if this could be more generic, e.g. tag any idl arguments as deprecated.
Tagging the IDL as deprecated wouldn't affect direct C++ callers in any way, right?
Yes it won't, and it's beyond the scope of this bug per se.
