I think the people appointed to the commission to study the federal court system were traditionalists like Biden who did not want to rock the boat.
The federal court system has long needed an overhaul, and not just for political reasons. Congress has not changed the composition of states in each circuit in decades even as our population has increased significantly and population shifts to southern states has meant that some circuit courts now have far larger populations to cover. The fact that cases that come before these courts can take five or more years for resolution is ridiculous. Several justices in these overburdened courts have written analyses and appeals for relief by at least appointing more judges have mostly been ignored, though I do agree that the recent effort to add more positions should have failed because it was based solely on Trumps wish to have more seats to fill.
I would like to see an analysis of the whole system of 13 courts by population covered with adjustments of states in each circuit to provide better balance and an increase in the number of judges to help carry the load. In addition, we should institute term limits fr all federal judges. .
For the Supreme Court, I would like to see 13 justices, one each to oversee the 13 circuit courts and term limits. In addition, I would like to see Congress pass requirements and definitions for judges to serve under the Constitutions good behavior clause, which should include ethics and behavior not representing one political party.
