Personally, I think this is a great idea.  It would allow people who 
need the low memory usage to transition over to the ext4 driver while 
keeping the memory usage low.  In such a case, I would almost suggest 
making an alias for the ext4 module (extfs maybe?) as modprobe ext4 
no_ext4 has the potential to significantly confuse people.
