Repeating myself - the 'defer' statement leads to no such issue or
expectation - as it is explicitly related to a scope exit and does not
promise to close anything!

In my opinion it is perfectly correct that the close method is not
invoked unless scope is exited. You just need to ensure that the close
logic is also invoked by the GC, which will presumably cleanup
everything eventually.
