But I don't see an advantage to that over just using classic COM at that point. This is only one handoff method and a rather simplistic one at that. Every benefit WinRT provides is outweighed by the extra effort that would be required over just a classic COM server in this case.~~
 - After delegation is complete, the inbox console will have to clean up any threads, handles, and state related to the session. We do a fairly good job with this normally, but some portions of the `conhost.exe` codebase are reliant on the process exiting for final cleanup. There may be a bit of extra effort to do some explicit cleanup here.

 The mitigation here, if necessary, would be to use `WinVerifyTrust` to validate the certification path of the `OpenConsole.exe` binary to ensure that only one that is signed by Microsoft can be the substitute server host for the application. This doesn't stop third parties from redistributing our `OpenConsole.exe` off of GitHub if necessary with their products, but it would stop someone from introducing any random binary that met the signature interface of the delegation methods into `conhost.exe`.

It doesn't really stop someone (or an attacker) from taking ownership of the `conhost.exe` in System32 and replacing it directly. So this point might be moot.

Given that the driver protocol in the box doesn't change and hasn't changed and we don't intend to change it, the forward/backward compatibility story is great here.

+1. We MAY have to enforce a scenario where we inhibit cross-integrity-level connections from being passed around. Generally speaking, processes at a higher integrity level have the authority to perform actions on those with a lower integrity level. This means that an elevated `wt.exe` could theoretically send a tab to a standard level `wt.exe`. We may be required to inhibit/prohibit this. We may also need to have one manager per integrity level.
 1. I'm not sure what sorts of ACL/DACL/SACLs we would need to apply to all the kernel objects involved.
 1. My initial prototype here used message-passing type pipes with a custom rolled protocol. If I make my own protocol, it needs to be fuzzed. And I'm probably missing something. Many/most of these concerns for security are probably eliminated if we use a well-known mechanism for this sort of IPC. My thoughts go to a COM server. More complicated to implement than message pipes, but probably brings a lot of security benefits and eliminates the need to fuzz the protocol (probably).

 We might be able to mitigate some of the reliability concerns here or even improve reliability by going a step further with the process/containerization model like browsers do and standing up each individual tab as its own process host.

 1. Process tree layout - The processes in hierarchy may not make sense to someone inspecting them either visually with a tool or programmatically
 1. Process and kernel object lifetime - Applications may be counting on a specific process or object lifetime in regards to their hosting window and we might be tampering with that in how we apply job objects or shuffle around ownership to make tabs happen
 1. Default launch expectations - It is possible that test utilities or automation are counting on `conhost.exe` being the host application or that they're not ready to tolerate the potential for other applications to start. I think the interactive/non-interactive check mitigates this, but we'd have to remain concerned here.
-1. `AttachConsole` and `DetachConsole` and `AllocConsole` - I don't have the slightest idea what happens for these APIs.
