Contrary to belief, rooting is not necessary to install a custom ROM on Android operating system regardless of what device is wanting a new ROM. The act of unlocking the bootloader and then installing a custom recovery is all you need to get a new ROM running. Root access does play a role in custom ROMs though. For example, if you were to head over to the Google Play Store and install the ROM Manager app you can use it to install custom ROMs instead of having to find what ROMs are out there and available for your device. An application like the ROM Manager is always going to need root access for it to work.
There are many other advantages to rooting the Android operating system that has nothing to do with new ROMs running on your YU smartphone. Most people root the Android OS so they can install more apps. There are apps out there on the Google Play Store that can do just about anything from backing up to tweaking the CPU frequency, so your device is clocked differently and even things to try to help increase the battery life. You can sometimes find apps to help with things like a battery as a non-rooted user, but there are always going to be better options out there with root access. Additionally, sometimes the same apps can work better if you have root access. Take the Dumpster app for example–an app that can help retrieve old deleted pictures that are no longer available on your smartphone. It is an app that is available for the non-rooted user, but people with root access allows the Dumpster app to dig a little deeper and retrieve even more than it would have without root access to the internal system.
