Indeed, if my understanding of this proposal is correct it will make 
working with multiple kernels much harder.

Making things harder to manage vs saving a little bit of space on the 
root partition really doesn't sound like a good idea; especially when 
with the ZFS install, which I would suggest is becoming the norm, the 
root partition doesn't suffer from space issues anyway.
