It depends what "security" means here. Pervasive monitoring (aka 
sniffing), that should be resolved on a hop-by-hop encryption, or MiTM 
that requires end-to-end encryption.

Having both hop-by-hop and end-to-end  would have been nice, but as a word 
of caution, compression of payload body in HTTP could be done using 
Transfer-Encoding or Content-Encoding. Almost no UA implemented TE:, 
almost no servers implemented Transfer-Encoding apart from chunking. What 
is widely used is Content-Encoding, and not without bugs (like issues with 
ETag handling), so like for https, the end-to-end version wins as it is 
easier to deploy/debug/control.

And saying that the only solution for people with poor bandwidth is to get 
rid of their security is not really satisfying.
