I would outlaw noun gendering globally. Does it serve any semantic purpose? It does damn good job at making learning unnecessarily difficult.

On a more serious note, it's a backwards compatibility thing. Taking a language with grammatical gender and removing it changes the way it looks and sounds rather drastically - more so for some than others. Needless to say, existing speakers are unlikely to appreciate it even if they don't care for gender qua gender.
