Allowing functions for Schema messages

Why can i give a function to a label, but not to an message? This currently doesn’t allow me to i18n the error messages like this:

regEx: [
        {msg: function(){
                return TAPi18n.__('forms.error.regEx.msg');
            }
        },
        ...
       ]

True.

But i would even though appreciate if i could define global schema messages the same way i can define labels, using a function:

SimpleSchema.messages({
    required: function(){ return i18n("my.label"); },
    minString:function(){ return i18n("my.otherlabel"); },
    maxString: "[label] cannot exceed [max] characters",
    minNumber: "[label] must be at least [min]",
