Open Q For Secondary Markets: Still Buying QM Assets?

Q for the mortgage industry: have begun reading early reports about secondary market players no longer buying (or greatly restricting) purchase of paper due to what is happening to servicers and an inability to even begin to calculate risk given the fluidity of the current situation. If true, the spigots will be shut off at the originator level shortly. This has basically already happened / is happening with almost all non-QM products

Anyone have a good industry shapshot on the secondary market Q demand analysis-- for QM products especially? Thanks all. The cure cannot be worse than the disease.
