Changed in 2023 in upstream likely means many users on mainstream
distros may still be using the old default.

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".
