Hopefully not. Our trainee teachers are managing to get in the classroom.Again, these extra staff don't really exist. I'm starting my first PGCE placement next week and I fully expect to be on covid marshall duties the whole time and doing fuck all actual teaching, still less learning anything myself.
Anecdotally teachers are already doing jobs like bus dispatching that they don't have time to do and aren't paid for.
It doesn't seem to be not enough teachers for classroom bubbles at my son's school, it was more to do with health and safety, first aid etc. So one imagines troops of support staff could be trained up and sent in, although not sure this is necessary because there are loads of teaching and support staff agencies with staff but schools don't have the budgets to get them in. Hence gov money.
