I know I did just that recently. SSE3 is probably too high for now.

I come from the days when a desktop PC cost $2,000. As far as I am concerned, that price never really went down. Not if you want a decent machine.
What changed is that these days you can get cheaper, crappier computers for a lot less. They aren't top of the line but they come in at about $500.
Or get a Raspberry Pi.
As far as I can tell GPU cost has gone up a lot. But if you wanted a cheap Intel or AMD system that is still very cheap.

Actually, no. The article isn't just talking about SSE2 hardware. It also mentions SSE3. I think SSE2 is probably in the reasonable realm since there's so many x86-64 baselines everywhere, and probably not very many x86-64 processors that lack SSE2. So they are matching in that regard.

Of course you do, at least you were honest enough to state your meaning. People throw around the "ancient hardware" moniker to the point that it's weaponized.
I actually think the skip between v2 and v3 is too aggressive because v3 omits AVX-only systems like AMD Bulldozer and Intel Sandy Bridge. There should be 5 levels; bump the current 3 and 4 up one and the new 3 should be lowest common denominator feature-set between Bulldozer and Sandy Bridge.
I'm old enough to remember when we'd get new architecture bumps every 5-8 years. I think we're going on 20+ years now. A lot of advancements have happened in those 20+ years and it'd be nice to take advantage of them globally versus rocking performance crippling legacy compatible code and having to get optimizations manually from elsewhere. That's why I keep proposing using legacy built packages as the base and having the package manager use the best optimized repo for the local CPU. No one gets left behind and everyone gets to run code more optimized for their kind of system.

So this is really only raising the default for 32-bit distros, which seems kind of pointless. These features are already enabled by default on x86-64, including AFAIU for 32-bit libraries.
If you're building a 32-bit distro you're probably doing it to support older hardware in which case you'll turn this feature off anyway. So I guess I don't understand why this change was made.
