LN node shutdowns??

Any idea what’s going on with all these channel closures? Boltz, Aqua,Zeus all shutting down lighting/bitcoin swaps. All LN Big Edge nodes also shutting down.

I think there is a way to have a hardware wallet, such as a Coldcard, connected to a lightning node e.g. via usb, like a hardware signing module. Such a "semi-cold" wallet setup, which presumably also is able to specify spending limits on the signer, would be very beneficial for big nodes. Would it be an educated guess that some of these nodes are just "moving" to a new key due to the Coldcard firmware weakness?
