Ah. What do you recommend for recipient to recognize such descriptors? Would they just try to seal them and reject them if this fails?
This highly depends on your use-case. Please see the initial email in this thread. It describes 2 example use-cases. In both cases, the recipients read the current set of seals and verify that a given set of seals is set.
I didn't find that very convincing. But in v2, seals are monotonic, so checking them should be reliable enough.
What happens when you create a loop device on a write-sealed descriptor?
