The search for exploits will not stop, but do not forget that the 3DS was released 4 years ago and we finally got to this point. You should always be wary about upgrading. If 9.6 comes out and there's no good reason to upgrade and there's no exploit for 9.5.0-23, you still should not update, because if we find an exploit that gets fixed in 9.6, then you'll probably end up regretting it.
The stock 3DSes at stores are still under 9.5.0-23, so you might be persuade a friend who wants to finally get a 3DS to have your old one if it is in good condition and let you have an as-of-yet unopened one.
