> It seems to be another golden age for iOS jailbreaking has came!
There is much, much less reason to jailbreak these days than in the iPhone 1 - 5 days. Unlocked iPhones are easy to get. Apple has copied a tremendous amount of features, and with iOS 13 having both dark mode and a fixed volume HUD even more reasons (Noctis / Eclipse and SmartVolumeControl2) are gone. And those, along with CallBarXS (call bar instead of fullscreen calls) and Jellyfish (weather on your lockscreen) are by far the most popular tweaks. I suspect at least the fullscreen calling will be redone in iOS 14.
Theming and game emulators will probably never come to the App Store, but those are even more niche. Terminal emulators and Python environments are already in the store. That leaves.. SSHing into your phone I guess, which is mostly a gimmick.
That's not to say the wild wild west wasn't fun back then. I remember both the Yellowsn0w and Redsn0w periods of jailbreaking vividly. Icy (a Cydia alternative) dying, being revived, and dying again. Down the nostalgia rabbit hole we go..
