There's actually a group of individuals who are in fact pushing to have accept rate hidden altogether. For some reason, users seem to give accept rate a lot of misplaced weight when determining whether or not to answer a question. As a result, I don't really see Stack Exchange taking the time to implement this feature.
In reality, an accept is only a mere 15 reputation, and the asker can only award it once. It's really not a lot of reputation when you consider that a well-written post that helps future visitors -- of which there will be hundreds or thousands -- could yield the answerer many, many upvotes. The potential for reputation on a decent answer could be 30, 50, 100 reputation or even more!
Instead of focusing on accept rate, focus on the actual question. Is it something you can answer? Is something missing from the question that needs clarification, and if so, could you leave a helpful comment asking the asker to provide that information? If all is in order, then answer the question. If it solves the asker's problem, they're likely to accept the answer. Maybe not today, and maybe not tomorrow, but that's okay. Remember, it's only 15 reputation.
Just this week, I saw in my reputation history that someone accepted an answer I wrote in March, over 7 months ago, and another was accepted that I wrote in April! When you've answered enough questions, even if you take a break, your reputation will continue to slightly increase, like interest paid on investments, and if I never took the time to answer those two questions because of accept rate, well, I would have lost 3 upvotes, plus the 2 accepts.
In summary, focus on helping people, focus on good Q&A, and the reputation will come. Don't harass people about their accept rate, and if you see these comments, flag them as noise. It's optional for users to accept an answer, and sometimes people won't know the answer worked for them until months later. So be patient. :) Hope this helps!
