Should I switch to xiaomi.eu based to my status?

[kuzyarl]

I am planning to switch to xiaomi.eu Dom on my POCO X7 Pro. I know that the xiaomi.eu ROM for mediatek devices are on patreon but before unlocking my bootloader and subscribing to patreon, I wanted to ask some questions. Thanks for the people helping already.

What are the chances of my phone getting soft/hard bricked?
Will xiaomi.eu get the HyperOS 3 update?
What services will I lose (like GPay)
What are the most dominant advantages and disadvantages
Anything else I need to know? I'm kinda newbie.

Thanks!
