Yes that makes sense. Now the search model is created in the ancestor view ... I think that would be less ideal. The model is very light weight and essentially only providing a bindable publisher and some (web) search functionality ... this probably doesn't need to outlive that view and it would be ok to create a new model alongside a view push ... Interestingly a TextField with the same binding to Retainer would behave as expected ... the model would be deallocated when the view is removed from the view stack ...

Looks like DispatchSerialQueue does not inherit from _DispatchSerialExecutorQueue as per documentation: https://developer.apple.com/documentation/dispatch/dispatchserialqueuehttps://developer.apple.com/documentation/dispatch/dispatchserialqueue
