End-to-end died the day the IETF published rfc1631.

In-line reassembly may be distasteful but in the scale of things it 
doesn't cause massive breakage for the types of clients it attempts to 
provide service to.

There are lots of other things that are far worse offenders, e.g. 
encoding transport endpoint values inside data streams (here's looking 
at you, SIP).
