T+0 all-year-round trading is good in many ways bad in others —like losing the real investor liquidity spawning window at 09:30 EST as opposed to pure market making.
Quarterly earnings were already a bad fit for many businesses so I agree with the measure to do away with them in principle. Someone proposed real-time and I think that would be a net positive if not very feasible. Yearly is a good compromise.
Companies that are not profitable YoY usually have a story so they probably can avoid having to rob Peter to pay Paul.
Then again, maybe everyone adapts and yearlies turn into the next quarterlies.
