I don't think it's a good idea to encourage people to allocate in
TopTransactionContext as a substitute for thought. One of the main
reasons for developing the memory context mechanism was to get rid
of transaction-duration memory leaks. People who want to allocate
storage that will outlive a single function call need to think about
exactly how long it needs to live and when/where/how it will be
released.
I agree that the particular paragraph you identified is oversimplified,
but the right thing is to fix the documentation not add another layer
of oversimplification.
