Any word on this? The time-saving value of Emmet expansions is exponentially increased when you're trying to type on a tiny iPhone keyboard!

OMG, please!

This should be easy enough to add, and ease the input process, which is always difficult in mobile. 

Much agreed on this, especially due to the size of mobile screens. Textastic has always come up with innovative solutions— specifically thinking of the swipe-to-symbol keyboard row, so something along those lines would be fantastic.
