Whilst this sometimes is what is required, I always suggest to people to remove this option and rather manage it by exception.
If you do leave this option enabled, it means if I had to share a report with Bob, Bob would then be able to reshare the report with someone else. This could potentially lead to other people gaining access to a report or data that they should not see.
Fortunately, I found a way to quickly remove the reshare option in the Power BI Service.
