1. The ROM is not so frequently updated because now it is not main interest of developer. But the thread is still lived.
2. Unfortunately installing such ROM require factory reset so you have to preserve your apps by means of Titanium Backup, Super Backup or another app. Futhermore any upgrade of ROM need the same operation. But IMHO this ROM is worthwhile.
Now onto my last concern: When you said "Futhermore any upgrade of ROM need the same operation", again I have to register the device with Google Account even though I have Titanium Backup of all my apps, right? This becomes a bit messy, when I look at list of devices in my Google Play store, I see so many... many of them are just 1 device indeed. Would same thing happen if I install MegaFire or MegaKat?
