I'm playing that piece too and love it - but my teacher has forbidden me using open strings for the D's as she wants me using lots of vibrato!
While it does need oodles of vib, especially on the minims (it is marked espr.), in the opening bar the D
quavers can be played quite poignantly on open strings. After all you have to play the G in bars 7 and 14 on an open string

so the tone will match.
Listen here, open strings on the quavers are good enough for VFV
