Unofficial and official are the same things at the end of the day. The only diff is the pain in the a** for who own the maintainership.
From our perspective, I thought an "official" ROM may have OTA updates. But, you're right: what's the point having a not maintained "official" release? 'cause at some point, I believe all "officials" would reach a dead end... The life is in that way
Just consider that only managing to achieve official recognizion it's not different to give birth. So it's totally not worth it in the end. Moreover, even having OTAs, in some specific cases (like last update) a full clean flash is required so no ota in any case.
let’s say because of security reasons. we are literally installing and using a software which a random stranger from the internet have built.
...and with stock ROMs we allow some others many more bad strangers watching us and sell our data.
Moreover, take note of this funny thing: i don't have neither the time, neither the will to make this "official", imagine having the time to write or modify full softwares for weird reasons lol. No thanks.
I don't want to root entire Android only for one Magisk module ):
indeed, it started doing that 2-3 weeks or so after installing the rom, temps seem normal during charging, so its pretty weird, im gonna try see how it behaves with the rom and if it keeps doing the same i guess im gonna try different usb cable/charger
