A very useful historical accident, I'd say!
But you seem against historical accidents. Ever heard phrases like "As it 
turned out, that implementation had more advantages than we forethought"?
I think this is one such case, as I've read no good (to me!) reason why 
this should happen.
For the disk space gain on /: the commands are doubled, but the space is 
reduced. This either means there are less programs in /rescue (whatever 
that will be called!) or that they are crunchgen(1)ed together. I don't 
think either is a good idea for the very same reasons that you all read 
countless times.
For the locale support: AFAIK, programs can be statically linked to support 
For the upgradability: I always used either binary upgrades or rebuilds 
from source. In either case there is no significant difference to me 
(except maybe for the download size, but I don't think that's a big issue). 
If anyone has another way or reason, I don't know.
For the rescuability (urgh :) of a system: I, right now, have on my system 
both /{s,}bin and /{s,}bin_backup, where {s,}bin_backup is a copy (n hard 
links) of the base directory. That way, should something go wrong with a 
bad sector, I will be able to recover the system (and I already did so). 
They're 15mb, ok, but I say a system's life is much more important! (and 
they can reside on another partition)
As for the network authentication, I really haven't understood well the point.

But I make the assertion:
/bin and /sbin are useful in single-user system recovery.
