The shape-note community, optimized for participation rather than 
professional excellence, does not appear to have an authority equivalent 
to Elaine Gould for its proprieties. I'm asking groups available to me 
how they see the unison-FA issue, no responses yet.

I do know this: the code comment from note-collision.cc that Werner 
Lemberg posted cannot be disregarded.

  /* The solfa is a triangle, which is inverted depending on stem
     direction.  In case of a collision, one of them should be removed,
     so the resulting note does not look like a block.
  */

I have experienced that thing. Once in a group learning a new song 
engraved with non-Lilypond software, we encountered what appeared to be 
erroneous rectangle LA shapes resulting from 2 wrongly-merged black-note 
unison FA triangles. It was a mystery to all except the few with 
music-engraving experience.

If a group of people with minimal music education wants to have full 
SATB or TTBB harmony by the second verse of a never-before-seen hymn, 
then this matters. For people with more music education and good 
line/staff unshaped-notes sight-reading skills, it matters much less.
