Yes, I have read that Weber had intended for her to die (following Nelson's trajectory) - (on, at least, two separate occasions) and, either, he didn't have the courage of his convictions, or else, he succumbed to pressure from fans and/or publishers by giving her a reprieve.
After all, she was a once in a lifetime character - a wildly successful one - that most authors can only dream of coming up with, and the books must have generated a decent income.
However, the Weber who could write such an impressive character as Honor - someone that many who read the series wished to emulate, (and some, as you have already mentioned, admired her to such an extent that children have been named for her) - and could write such fully realised, three dimensional Peep commanders - failed utterly when writing this relationship.
He failed Emily (who deserved far better), he failed Honor - nothing in her character portrayal suggests why she would consider Hamish attractive as a partner in life, a romantic partner, - and he failed the story, which had been brilliant until then, because he couldn't square narrative demands (be faithful to Nelson's life) with Honor's ethical and decent character.
Hence, the tree cats and Emily being twisted - pretzel like - into conferring approval on an appalling relationship.
