Retention of metadata may not even be considered a search or seizure, it's unclear to me how likely it is that it might be declared "reasonable", taking it to the supreme court would require many years of work during which irreparable harm would be done, and whichever parts of the law were struck down it's likely that others would stand — and every part of it is irredeemable.

The whole bill is so blunt, crude, and stupid that I think there's hope that it might be somehow arranged that it gets stuck in committee until it's forgotten about.
