Hi Matt,
The main problem I see with that suggestion is that it requires an extra keystroke where none was required before.
It's not a big deal, but the reason why I like the current default is that it saves me keystroke and brain power. For me, that wouldn't be much better than just typing <- manually (which I need to do anyway when I'm using R without ESS).
