It's not. Marlene or Sasha (can't remember, but I think Sasha) said in an recent interview that due to Alison coming back, all remaining relationships of the girls at one point will be stained.

So Caleb could still be a part of that. Toby and Ali, Ezra and Ali have history and are now the (ex) boyfriends of her best friends. And Emily and Alison still have some unfinished buisness with lingering feelings. Maybe Hanna will not necessarily be jealous with Caleb/Ali, but maybe they have some interaction that still stains their relationship.
