I'm not sure "integrity" is the exact word I'd use. 😄 Nevertheless, rather than editing this one:
as he mentioned in a letter
I see I was wrong about this too; it's actually a note by Christopher in
Return of the Shadow :
I was greatly delighted by the story of Bingo's turning the tables on Farmer Maggot, and while I retain now only a dim half-memory I believe I was much opposed to its loss: which may perhaps explain my father's retaining it after it had become apparent that it introduced serious difficulties.
Page 297, Note 13
The "serious difficulties" had to do in part with who knew about
the Ring, and when, which I won't go into, but the encounter with Maggot, and Maggot himself, went through several stages in the drafts.
Originally,
Frodo (still "Bingo" at this stage) wants to avoid Maggot's farm simply in order to not to be seen by anyone, and actually
puts on the Ring -- as he had also done when the
Black Rider came by. He plays a trick by invisibly drinking ale from a mug, supposedly because he was miffed at the others being able to drink while he stood there (at this point, the other
hobbits know about the Ring, and he knows they know). Maggot, being astonished, asks that they leave.
In a later draft, Bingo confesses that he'd killed one of Maggot's
dogs as a boy, leading to the beating as in the published text. In this version, "Maggot becomes a violent and intransigent character, with a black hatred of all Bagginses":
'He beat me, and told me he would kill me next time I put a foot over his boundaries. "I'd kill you now," he said, "if you were not Mr. Rory's nephew, more's the pity and shame to the Brandybucks" '
Page 289
The "trick" also escalates, with Bingo shouting at Maggot and pushing him into the fireplace.
In yet another version,
Bilbo had been with Bingo in the trespass, and it was Bilbo who killed the dog with his stick, whereupon Maggot picked him up and threw him over the hedge into a ditch, followed by Bingo. As Christopher notes, he'd become a "real ogre".
Which leads to something at least relevant to the ancient OP: the idea that Maggot was
not a
hobbit, or only partly so. A note by Christopher has:
The division of hobbits into
Harfoots,
Fallowhides, and
Stoors had not yet arisen, and the fact that some of the people in the Marish were 'rather large, and heavy-legged, and a few actually had a little down under their chins' is ascribed to their not being of pure hobbit-breed.

And in an outline for the
Tom Bombadil chapter,
Tolkien had written:
He turns out to know Farmer Maggot. (Make Maggot not a hobbit, but some other kind of creature -- not
dwarf, but akin to Tom Bombadil).

So it can be seen that the "mist" existed for the author too.
