Maybe, but I doubt Cobain cared that much about some small-fry people from Olympia anymore. Relations with the Calvin group got sour after he found fame.
In Utero was a mixed bag of a record, meant to destroy this perception that they became a mainstream band. But it's also a parting shot, a fuck-you record on which he put some half-assed songs that were literal improvisations in the studio. Alongside Nevermind-era classic compositions like Dumb or Pennyroyal Tea.
I don't think he cared that much what people thought about it, even less what some guys in Olympia did. He had a plan to stage his exit and the album had enough songs with some hit potential to secure his family some revenue for him to leave them something.
