Just out of interest, where is the code that raises the AP network  
authentication name/pass request? That feels like a pretty close  
template fit to such a critical warning.

I must just say I'm not 100% convinced about how successful a warning  
will be (but it is better than nothing). I've hit the issue a couple  
of times and it was not some slow incremental case where I could take  
sensible action. Both times, as I recall, I was downloading some  
~large library or binary which maxed out the space in one go before I  
realised the size.
