Now I’m wondering how representative those two hymnals are.
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.
