Your comparisons are absurd, we are talking about a software framework here, not OS's or video games. I think an apt comparison would be JVM, CLR or the Chromium JS engine. Those things are constantly performing better and new features are being added.
Ext4 doing a lot more is debatable, you can produce the same guis in 3 that you can do with 4 and I am assuming that goes the same for Ext 2 as well. I want to say that from Ext 1-3 the performance constantly got better, Ext4 is much slower but to be fair it is still has time to catch up. I wish I had a link to a graph I saw a while back which plotted all Ext 1-4 stuff out.

The same is true for any software. Just because something meets the minimum requirements does not mean everyone should expect it to perform the same as a prior version on the same hardware. As far as I'm concerned, this is so obvious that it's rhetorical.

If Sencha flat out said, we are dropping IE6 support to make our software better, I think everyone would rejoice. At least we know what to expect and make our decision to upgrade based on that.

Check out the performance numbers of V8, they constantly get better on the SAME hardware, I expect similar numbers would show for the JVM and CLR. Not sure how you can gloss over the points that Ext got faster from 1,2,3 on the same hardware or the fact that many other frameworks and engines get faster over time on the same hardware.

It seems that either you're not understanding what I'm saying or you're just ignoring what I'm saying. Would it be great if Ext JS 5 were faster than Ext JS 4 on the same hardware? Of course it would. But it's very difficult to do if you're expanding or improving the features, not just UI features but underlying core things like the class system, because there's just a lot more going on under the hood that you don't even see. I'd much rather have Sencha focus on expanded UI capabilities and a more powerful class system than trying to optimize the way it runs on outdated browsers and hardware.

I'm sorry I think you are trolling at this point you compared Windows7 and Win 95. You completely ignored the point of V8 getting faster and Ext 1,2,3 getting progressively faster but able to produce same gui's but I don't expect you to address those points because you can't.
Yes stuff has changed under the hood, the class system is nicer but the layout system is much more complicated under the hood and slower.
Agreed, I wish they didn't bastardize the entire code base to support old platforms and technologies (Tables everywhere for layout and IE switch statements). Also keep in mind that 4.2 is slower than 3 in Chrome, FF and other browsers not just IE.
