Besides all the foreshadowing about Quirrell’s plan being to lose a battle to Harry, isn’t it rather convenient that Quirrell just happens to arrange for Harry to learn the spell that Harry uses to defeat him?
Not really. Mind magic is one of Harry’s top priorities, Quirrell is the first person he’d ask about Obliviate, Quirrell has no reason not to tell him, and Obliviate wasn’t exactly the spell Harry used to defeat Quirrell in the first place. This outcome is about as likely in the world where Quirrell wasn’t expecting to lose as in the world where he was, so it doesn’t shift the priors substantially.
