There are many scenarios where removing one or many participants may substantially change the line up of the bundle in a way that may be misleading to the other participants. I could imagine us adding something in the future that lets you remove participants if it represents under a certain percentage of the total bundle.
A follow up question I have is why are are there people in the bundle you have organized who don’t end up approving the bundle? Were random people added with the hope that they would participate?
I can’t imagine why you would see the approval process as a means to “annoy” others unless you’ve invited untrustworthy people to the bundle.
