I would prefer to avoid adding methods to the API when methods
already exist that serve this purpose, even if their names aren't
ideal.

No, in the stream API the behavior of each method is well-defined
irrespective of order. If you call don't call close() at the end,
nothing bad happens. If you call close at the beginning the
read()/write() methods still behave as documented. No method fails to
do its job simply because its called before or after another method.
The larger program that uses the class may depend on a specific order
of method invocations. However, the class itself exposes only atomic
operations.

I'm not sure we need two methods here.
