The arrow keys don't have any meaning after C-x 4 today, and the meaning I've 
been wanting to give them is useful and logical. I've been using the arrow key 
setup for years locally and it works very well. It really does make window 
management much less annoying, and it's not like we're going to use the arrow 
keys for anything else under C-x 4.


As for windmove being used by users --- well, wouldn't it be nice if we had 
metrics like other modern software projects? But that aside, even if windmove 
is sparsely used today, might that be because it's inconvenient to use without 
bindings? Your argument is a general purpose argument against having default 
bindings, isn't it? Key bindings are precious, and we shouldn't waste them on 
unimportant things, and if the things were important, we wouldn't need default 
key bindings for them anyway because users would have already created their 
own. The argument seems a bit circular to me.
