First, we can't go back to old-style terracing. In the 1970s, crowd violence increased a lot, and crowds seriously dropped. You daren't take your kids to a football match any more. So clubs themselves began to introduce all-seater stadiums to cut that down. Clydebank were the first in 1977. Aberdeen made Pittodrie all seater in 1979 with benches (replaced by individual seats in 1981). That same year, Coventry made Highfield Rd the first all-seater in England. It wasn't the Taylor Report that started that - it was increasing social indiscipline in Britain, and the damage it was doing to club gate receipts. After Hillsborough, Taylor just latched on to what Clydebank, Aberdeen, and Coventry had started some ten years earlier.
This safe-standing idea might be ok, but you'd still have to keep home and away fans separate. Mixed terraces - and the non-violent banter that went with them - are never coming back now. We've lost something from football forever. Safe-standing is a compromise, and might be o.k., but I'm not thrilled. It will give people choice though.
