 Optional features:
 
 - `1 GB` huge pages (aka `PDPE1GB`) wide support since 2012 and used as optimization
 	- May be not present on virtual machines
 - `x2APIC` is optional on AMD and **used** by Greentea if present

 Not required features:
 
-- `SSE4a` seems like AMD-only and **not** used by Greentea
-- `AVX2` introduced in 2013 and **not** used by Greentea (available for third-party apps)
-- `AVX-512` introduced in 2016 and **not** used by Greentea

 This project started as a controversy to undefined future (and past) of existing operating systems.

+Some features aren't really useful in any real manner *right now*, and their priority may be lowered.
 
 **Update from 2023:** seems like M1 CPUs finally make ARM support valuable?

 so can't be considered in any manner real target for Greentea OS team and use case for our users.
 Also, multiply that by a *enormous* number of bugs, hacks and workarounds, which we should fix now,
 to at least make non-academic project! And then improve implementations, **the real things**.
