There is a risk even with non collateral assets.
When someone borrows ampl, manages du dump the price and withdraws collateral the protocol is left with bad debt if the price recovers faster then liquidations are performed. In the current CRV bad debt situation caused by Avi, CRV was not used as collateral either.
I’m personally not in favor of re-enabling v2 or listing on a v3 with current mechanics. I think there’s no other asset that caused a similar amount of frustration in the community. Perhaps one could consider wrapped ampl though.
