Consequences would be nice, but actually forbidding it for the future would be enough. Obama promised to do it, but didn't, and everybody kind of forgot and moved on.
We sure did when Frank-Dodd was written by the legislative and then signed into law by the executive.

The legislative produced Frank-Dodd...which Trump and Republicans later scaled back...
