Edited the original post for the sake of clarity and to not shame you with my horrible work 
Wouldn’t something like this be more resilient then?
@impl Application
@spec start(any, any) :: {:ok, pid} | {:error, :ignore | any}
def start(_type, _args) do
case System.start_link() do
{:ok, pid} -> {:ok, pid}
:ignore -> {:error, :ignore}
error -> error
end
end
Or doesn’t it make sense at all?
