I'm answering the question a bit late, but here I come.
First of all, griefing does not exist. This "term" was invented by fragile people who had to find a word other that "I'm stupid" to excuse the fact that they clicked on Open Play and faced PvP players in an open world where PvP is possible. If you don't want to take the risk of PvP interaction at any time, stay either in solo or private groupe, or assume the fact that you can be killed, in no case it's called griefing as you have to free choice to avoid these interactions thanks to both solo and group mode.
That's not answering the question that is offering your opinion to the matter, by the nature of your signature and comment above it I can tell that you chivalrous to a fault.
egg chicken, chicken egg, with the rebuy costs open will be empty space very soon, the intake of new players will drain out and existing players have high insurance premiums and avoid players of your mindset. Game over get BF1 out of its wrapper.
