I guess it'll depend on how hard this is to implement. At the moment  
I'm dealing with lots of Lie brackets so I'd certainly appreciate  
this feature very much ... in my opinion it would also improve  
consistency: the same markup works for any kind of formula!

On the other hand one could also enforce the use of \[ whenever the  
glyph [ should be actually typeset. This would be the other road to  
consistency ;-)
