Seems to just be making it more complicated for newbies.....it's all very well if you know your version, but what about those who don't?

Re: amdV3 - amdV4 etc?

Those levels were invented a few years ago by "bigtech" to obsolete older hardware and force people to upgrade to newer PCs now that the switch from 32 bit to 64 bit is no longer enough to obsolete additional older hardware. It's sort of the next step after stopping support for 32 bit cpus.

IBM (Redhat) and Suse have already gone down this road, their recent releases don't work on older 64 bit cpus any more.

I see it as a good reason to become more independent from the corporate Linux world (primarily IBM/Redhat, but also Suse and Ubuntu) and focus on pure community run distros that don't have agendas and profit motives.

That said the way Ubuntu is currently approaching this for now is sensible, as they are building packages for the different levels, so for now they aren't obsoleting older 64 bit cpus, but the cinic in me makes me think that this is just a "boiling the frog slowly" approach to avoid a shitstorm, i.e. in a few years they will likely be discontinuing support for older variants. 

BTW, wikipedia lists who is behind this:

In 2020, through a collaboration between AMD, Intel, Red Hat, and SUSE, three microarchitecture levels (or feature levels) on top of the x86-64 baseline were defined: x86-64-v2, x86-64-v3, and x86-64-v4. These levels define specific features that can be targeted by programmers to provide compile-time optimizations.
