Auto-spacing of lyrics is non-ideal

I don't know if this is an 'issue'/bug report or a feature request. I have lyrics attached to a vocal line and a piano grand staff underneath. The layout and spacing favours the piano part over the vocal, which means the spacing between lyrics is not good. In the attached example, the words 'to you' and 'to who' are very close together. The straight eighth/sixteenth notes in the piano are spaced evenly, and the vocal dotted eighth-sixteenth notes align vertically to the piano part without making extra space for the lyrics.

Perhaps there should be a 'margin' attached to the left and right of each lyric segment? For example, the default is something like 0.2 sp or whatever on each side. If the lyric segment ends in a -, then the right spacing defaults to 0. If the preceding segment ends in a -, then the left spacing defaults to 0.
