Why Redmi K40S/POCO 4 (munch) has HyperOS?

[RedstoneEnjoyer]

I'm genuinely wondering why we have HyperOS release for Redmi K40S/POCO 4 (munch). I've been looking for official HyperOS releases for this device and found none, yet here it is with xiaomi.eu.

I want to know if it's safe to update and if there would be any updates for that in the future (since the ROM's looking like being discontinued for a while).

Because it is used as the basis of CN ROM Redmi K40S which is already officially released unlike the Global ROM for Poco F4.
