It's a matter of convenience. Sometimes you're just interpolating bytes
data together and it's a bit suboptimal to have to do a
decode()-encode() dance around that.

That said, the whole issue is slightly overblown as well: network
programming in 3.x is perfectly reasonable, as the existence of Tornado
and Tulip shows.
