This configuration variable should be avoided, it is bringing more complexity to the config - it opens the door for creating thousands of variables of the same category, would we normally create a config variable for every error message we have in the system?

[utnapischtim]

this is true, and the configuration variable is not necessary since you can always override what should be translated. this works for the English language too.

so this config variable is not necessary this should be replaced with the value of the variable
