Oh, so we're playin Inception at a whole world scale. Nice.

Xmanager doesn't compile the apk. I downloads the same files you have on telegram.
The main advantage of it over manually downloading the files is somewhat easier usage and update notifications.
Do you have the full resolution?
No, sorry. Airplane mode should stop all data exchange with mobile radio, but you should still be able to enable wifi and bluetooth while airplane mode is on.
I'm pretty sure all communication with carrier is disabled when airplane mode is on, which should save more power than disabling only mobile data transfer (in this case calls and messages still get transfered and connection with carrier is active).
Unless you completely power off the radio you will still receive calls and messages. Some custom roms come with this option, but I don't know if it's possible to automate.
If you want to save more power, then enabling airplane mode and then turning wifi and / or bluetooth (depending on your needs) back on should save more power.
I think the situation here is similar to Telegram. Russian connections, but not in a impactful way. I use both without worries, but if this doesn't suit somebody, there are alternatives.
That's your decision. I experience no issues with my setup, but you do what you want.
There's something interesting about mobile banking. I constantly see stories of issues with it on non-stock / unmodified software. The funny thing is that I have never had any issues personally. Until recently my banking app worked even without Magisk's Denylist (and the most picky app was McDonald's). Now (since few months) I have to add it to Denylist, but that's the only requirement, no SafetyNet, no Play Integrity, nothing.
KernelSU? Hadn't heard of that one before.
It's relatively new, few months old at most and started as a joke.
Do you get proper compliancy with the Integrity API?

Feel free to ask more questions if you need. For me getting to this point was quite an experience, so I'd be happy to help.
That was 3 months ago.
My phone is Redmi Note 10 Pro (global version) running a custom ROM (AOSP based).
You can install KSU on non-GKI devices: https://kernelsu.org/guide/unofficially-support-devices.html. I was probably using this one, but there are multiple KSU kernels available for my device and you can probably find some for yours in the telegram groups.
