I sense that an unusual perception of risk is influencing performance selection.
Past safety initiatives have focused on the hazards of RTOs from higher speeds.
Whilst statistically there could be concern, it does not follow that these accidents are related to the performance aspects of engine failure.
Data suggests that the likelihood of an engine failure is low in comparison with other issues, and those engine failures which have contributed to accidents occurred after rejecting above V1.

Furthermore, much of the 'go minded' mantra plays-down engine failure and performance issues - see briefing note:

https://skybrary.aero/sites/default/...kshelf/197.pdf

whereas,

"… transport aircraft in Performance Category ‘A’ should be able to safely reject the take off if the decision to do so is made at a speed not greater than the correctly calculated decision speed (V1)."

https://skybrary.aero/articles/rejected-take

For engine failure at any speed below V1, a 'go mindset' has no place in our thinking - its mental clutter, which encourages an incorrect response.
