That's also a possibility. But then I think it would be better to keep the old 
name for the default rounded-box hyphen and
ly:lyric-hyphen::print-text for the now code.

Yes, I also added text-interace to LyricHyphen, but a default value for text 
"-" needs to be defined somewhere:

    (LyricHyphen
     . (
        (after-line-breaking . ,ly:spanner::kill-zero-spanned-time)
        (dash-period . 10.0)
        (height . 0.42)
        (length . 0.66)
        (minimum-distance . 0.1)
        (minimum-length . 0.3)
        (padding . 0.07)
        (springs-and-rods . ,ly:lyric-hyphen::set-spacing-rods)
        (stencil . ,ly:lyric-hyphen::print)
        (text . "-")
        (vertical-skylines . ,grob::unpure-vertical-skylines-from-stencil)
        (thickness . 1.3)
        (Y-extent . (0 . 0))
        (meta . ((class . Spanner)
                 (interfaces . (font-interface
                                lyric-hyphen-interface
                                lyric-interface
                                spanner-interface
                                text-interface))))))

Cheers,
 Knut
