WI: Penal Laws not repealed?

Just like the title. What if the UK didn't abolish the Penal Laws that discriminated Catholics? What would it look like as it goes I to the Victorian era?
There’d probably be protests about it by the English Catholics, and rebellions of varying degrees of success by the Irish Catholics.
Irish revolts were a fact of life (last in 1798).

This might well butterfly the 1832 Reform Act, since the opponents to Catholic Emancipation thought that Reform would enable them to rally Britain's Protestant majority against those pesky Catholics. And without 1832... 1848 just gets interesting.
