Well, \addlyrics only works in the most simple cases, so there's a point in 
presenting \lyricsto instead.

BTW, the following template:
http://lilypond.org/doc/v2.7/Documentation/user/lilypond/Single-staff.html#Single-staff
does a \context Voice=one{} without explicitly creating the surrounding staff. 
I'd recommend to add a \new Staff, like:
        <<
           \new Staff \context Voice = one {
              \autoBeamOff
              \melody
           }
           \lyricsto "one" \new Lyrics \text
        >>

Anyway that's what I usually do. It "feels" unsafe to use \context Voice alone 
to create a new staff, it "feels" like that context could end up in an 
already existing staff if more parts are added to the score in a similar way. 
Consider the following, for example:
        <<
           \context Voice = one {
              \autoBeamOff
              \melody
           }
           \context Voice = two {
              \accomp
           }
           \lyricsto "one" \new Lyrics \text
        >>

I think lily does create separate staves for the voices in this case, but it's 
not at all clear, and adding \new Staff statements explicitly makes the 
semantics clearer.
