Host reject to freeze?

[Jack-Works]

It might be possible there is a host API like this:

const process = new Process('./native.so')
process.memory instanceof ArrayBuffer
process.memory.transferToImmutable() // or .detach()

Is this a case we want the host to be able to reject the detached behavior? (This also affects other APIs like transfer actually).

I'm confused, how would this not work out of the box? If it's actually a proper instance of ArrayBuffer, then it'd be detachable; if it's not detachable, then it's not a proper instance of ArrayBuffer.

I mean, if there is a case that the host wants to reject the AB being detachable. this is like HostEnsureCanAddPrivateElement that limits the ability of adding a private field to a host object.

Why would we want to consider a host hook when no use case for that has presented itself?
