These rules are going to be gone when the GOP takes back the House. I don't see how this isn't bad and pretty much blackmailing Pelosi.
People keep asserting this, but I don't think there's any evidence for it. Once you enact a reform that strengthens individual members, it's very hard to get individual members to roll it back again.
Also, frankly, I don't actually think Pelosi needs the power to stop bills that a majority of Congress supports from becoming law.
