I don’t think they should limit jurisdiction. In short, that creates utter chaos. What, whoever is in power both gives and takes and changes jurisdiction?
No. BAD idea.
That's the government system intended by the Founders.
Possibly you should consider starting a drive to amend the Constitution appropriately to remove the power from Congress.
Probably not necessary, since I believe the power has only been used twice, not for 80 years, and then in rather limited fashion.
