I very much agree, but (1) you described that the goal of this document was to get the users going as quickly as possible, and giving them the securest possible setting is out of the scope, and (2) we would need to think what to do with the example in the next step if we leave it the default here. The answer to the latter could be to update it to "something like ... but the filename may differ depending on the default type of the key".
