Right-- the problem statement was:
Compared with past years, the 2020 game poses a greater [1][2] operational risk that teams choosing to target the retroreflector with bright, visible lights will be prevented from doing so due to a concern about the safety of that light exposure (intensity * duration).
[1] The goal is located above the opposing alliance’s driver station.
[2] It is reasonable for an alliance to be attempting shots throughout most of the match.
If IR is no safer than visible light, then it isn’t a solution to the problem statement.
