XIAOMI.EU FOR REDMI NOTE 8 (2021) BILOBA?

[Naxarexx]

Since they announced that they would support cell phones with mediatek, I have been waiting for confirmation of the list of all cell phones with MEDIATEK (MTK) processors that will support them, since I understand that starting this year they would start developing the ROM for These devices

Then you should read carefully. Support for any MediaTek Helio device was never even considered.
The announcement says "select MediaTek Dimensity devices".

Community-funded MediaTek Support Initiative

We have launched a community-funded initiative to support select MediaTek Dimensity devices. The details are in the "About" section of the Patreon page: https://www.patreon.com/xiaomieu

xiaomi.eu

And if you check the introduction in the Patreon page, it specifies further that only mid-tier and higher MediaTek Dimensity devices are considered.
There is no static list of which devices will or will not be supported. We can start supporting a device if enough contributors join to support it, or terminate support for a specific device if it has no demand (= not enough contribution for support to be worth the effort).
As you are not a contributor, you're not taken into account when making any decisions regarding this matter.
