PW5 Is jailbreak pointless this days? Librariansync not working

Hey,

I jailbroken my PW5 as soon as jailbreak dropped (around 2 years ago) to use tweaks like librariansync or screensaverhack as these two were my biggest pain in the ass. I was really disappointed to see that none of them works and 99% of tweaks are not updated for PW5...

Whats the point of the jailbreak then? What I can do with my jailbroken PW5? Starting to think about getting back to OEM soft...

Thanks in advance for any help and suggestions!
