A fudge will be announced on Wednesday that sees teams having to run with higher pressures/lower cambers and the teams will miraculously agree that changes are needed but it will be framed in such a way as to avoid the tyres being deemed unsafe.
You're probably right, and since the tyres can't be changed for Nurburgring I actually think it's sensible, since it's a much easier circuit on tyres than Silverstone anyway, to go ahead but to take whatever other actions are possible to mitigate the risks, in particular minimum pressures, maximum cambers and grinding down kerbs to make them flatter and take away sharp edges. And Charlie will have to be extra-vigilent - as soon as there's a tyre failure, instant SC so the track can be cleaned. And if the pack cannot avoid driving through the debris, throw the red flag so the tyres can be changed. But the tyres must change for the next event: presumably this will be decided on Wednesday.
What I am worried about is the notion that Pirelli will be allowed to not admit there is a safety issue. The governance structures of F1 crucially rely on the FIA to take overall responsibility for safety and to be able to impose any change it wants without the need for notice or teams' agreement in the interests of safety. They can't do that if the tyre supplier is going to deny obvious safety concerns and the FIA is going to be too polite, or too scared of being sued, to contradict them. One would hope the tyre supplier would be responsible, and would realise that when there's a problem the only way to get the necessary changes done is to come clean about the fact that there is a problem. If they have done this straight away the damage to their reputation would have been minimal. The damage to their reputation now is huge, and if Fernando Alonso had suffered Massa-type injuries as a result of being struck by Perez's tyre, the damage to Pirelli would have been 100 times worse again.
If Pirelli are not prepared to be responsible about this the FIA should publicly declare that in its opinion there is a safety issue, demand that it is fixed, and decline to renew Pirelli's contract. The kind of behaviour Pirelli is engaging in undermines F1's governance arrangements by effectively making safety-related changes impossible without the teams' agreement, which is unworkable and is the complete opposite of how the system is supposed to operate.
