In English novels, this coyness device and others related to it starts early, with Defoe and Haywood et al. This is where it comes from: Novels in early genres, especially courtship novels but also racy novels and social novels like Defoe's, posed as actual found documents, manuscripts discovered by the 'editor' (author) - dairies or letter collections or memoirs - which the 'editor' believes should be published for the edification and entertainment of the public. That pose quickly becomes conventional. To protect the privacy of the real human beings whose writings/stories the novels pose as recounting - and to 'prove' the 'editor' is making the ms public for disinterested motives and not prurient intentions or to sow scandal (developing the editorial/authorial persona of novels) Mr B-----'s name, for example, (in Richardson) goes undisclosed, and actual places are also disguised, giving the impression of a text delivering something like gossip (the dash was common in scandal sheets too). The dashing out of place and proper names was also common to 18th c. pornography.
By Austen, the practise of concealing identities/places is vestigial, but still has a bit of an impact suggesting the 'truth' - an early gesture to realism - of the story being recounted (and delicacy with regard to the characters) although arguably at this point - Austen - it's having an opposite effect - the disturbance of the illusion. But its still pretty natural for novels posing, with varying levels of self-consciousness, as found documents...or satires of such...while for the realism of which Austen is an early practitioner, its begun to look weird.
I can't be certain, but in those early days of modern fiction, creating your own borough out of thin air might have been too much for some readers, interrupting their suspension of disbelief. The same might happen if you wrote about fictional people in real places. "Cor, my sister never heard of no Bixbys down at Glouster."
You can think of it as a primitive device akin to today's metafiction, with "real" documents trying to fix a story in reality. "I'm telling a real story, but certain names are changed to protect the identity of those involved."
