Yes, but it would be easier to move about than an allocated seat.
This is still a major concern for lots of us. I haven't been back in the stadium despite being double jabbed. Certainly, won't be more likely to return with this proposal.
I think I must be missing something here. Movement along safe standing terracing is exactly the same as movement along seated terracing.
People walk along them in exactly the same way. One foot before the other. You're still allocated a specific spot.
The only difference being seats will be locked in the up position and there'll be rail bars between rows to prevent forward crushing. That's it.
