It's on BA to keep up with this, but certainly R-C would be cognizant of blow-back if a crash occurred due to some failure among nearly 800 installed not-yet-approved units.
The Rockwell Collins brochures make them seem like really nice additions, but I suppose the value is in what the pilot learns to do with them.
The 737NG had HGS (HUD) installed before 2015. The HGS/HUD was updated on later 737NG's to the best of my knowledge.
What the "pilot learns to do with them" (your quote) is taught in a separate simulator detail which includes a demonstration of a Cat 111 approach hand flown to minima.
The HGS/HUD displays a flare cue during the landing, amongst other details. The HUD also displays AOA, wind shear pitch commands, tail strike and a whole lot of other valuable features for the Captain only, as there is no HUD repeater on the FO's side.
