According to this article, "becoming more diverse" is a goal of the NFL. Right now, nearly 80% of NFL players are black; just scroll through the article's "playmakers" section, see how many white players there are: is the NFL starting "initiatives" forcing teams to consider white players before black ones, to try to get closer to 50/50 player representation?

The article also states that the league will continue to make more rule changes "whatever this season's [injury] numbers show". The NFL rules people always claim to be "data driven", yet I can't remember the last time I saw someone injured on a kickoff versus other situations, like offensive linemen getting rolled over from behind, or running backs hurting knees during jump cuts. Like most institutions today, they seem more concerned with perception ("at least it will look like we're doing something") and virtue signalling, than reality; it's easy to change the touchback line (even if it doesn't help a darned thing or is even counter-productive), but difficult to outlaw jump cuts.
