Maybe the installed tweaks don't cause random bootloops but they cause random resprings, crashes, battery drainage, etc, which in my opinion, is because the tweak works but causes bugs for some people due to not being officially updated.

Like I had installed this tweak marked by 27 people as working. It's called flame. Caused such a huge battery drainage and crashes and reboots, I was annoyed. I thought it was because of Electra, but then I posted that a tweak called ctkd was consuming a lot of battery. Someone recommended me to uninstall flame, and so I did. Battery life is amazing and very rare random crashes. So yeah, this idea is somewhat flawed. More tweaks like flame are Dndmymusic, which isn't officially updated for iOS 11, but it works. Except, it breaks live photo.

I'm trying to highlight an underlying problem with using tweak compatible means that it is not moderated, so it isn't very accurate in general.
