I found a decent introduction to pure properties in the CG (10.13).

    One last oddity is that purity, in LilyPond, is currently
    limited exclusively to things that have to do with Y-extent
    and positioning. There is no concept of ‘pure X’ as, by
    design, X is always the independent variable (i.e. from
    column X1 to column X2, what will be the Y height of a
    given grob).

This seems to support my conclusion that no further work is required.
