This was discussed in ENG-7133.
Note that on web, keyserver session aren't currently invalidated via useKeyserverRecoveryLogIn, as we aren't able to attempt recovery since it depends on having access to user credentials. This will no longer be the case following the identity service launch, since user credentials will no longer be necessary for attempting keyserver session recovery. As such, I'm not going to bother doing anything special for web, since it will be supported via this mechanism relatively soon.
Depends on D11264
