This is all quite off-topic, but…
That was the older, nicer Apple. You really think we'll get an emulator for older apps? I'd be thrilled to get such a compromise... I do remember running Power apps on Rosetta - and it generally worked.
Apple didn't give us an emulator for the 32-bit x86 Apps we depend upon,
Rosetta was available between 2006 (Tiger on Intel) and 2011 (pre-Lion). That was basically the transition phase. For 32-bit x86? There were
ten years for third parties to get their act together and compile for 64-bit.
I know we're losing some software along the way, and it sucks, but it's not like Apple suddenly made a cut-off. 64-bit x86 existed in Snow Leopard in 2009, and 32-bit x86 was removed in Catalina in 2019.
And why aren't they, when Mojave is clearly using such an emulator?
No emulator.
Apple doesn't want to maintain the 32-bit runtime any more, because in general, that comes with overhead, and in this particular case, there were backwards compatibility concerns that meant they could never resolve some issues with it. Moving to 64-bit gave you a much newer runtime for free.
Because they want to FORCE us to use new software. To Force us to use the new APIs. To give iOS cross developers a leg up.
This has nothing to do with iOS at all, but yes, generally speaking, a framework vendor wants third parties to use newer versions. Not doing so is an engineering nightmare.
We can quibble over details like whether Apple should be able to handle it, given their amount of money, or whether they should be shipping an emulator. But I don't think the general idea that old stuff needs to be deprecated at some point should be up for debate. It's how engineering works.
You can't even use a VM like VMWare fusion, because they don't support the graphics APIs, so the apps simply crash. And their advice? Keep around an older Mac to run the Apps you love.
I think it would've been nice of Apple to provide a VM of their own, but it's not their fault if VMware doesn't work well for this job.
I think this has been a big deficit in Apple vs Windows for decades - Apple has never tried very hard to keep old software running, even when it was a simple independent app like Rosetta.
Microsoft sometimes screws this up as well. Windows Phone 8 phones couldn't run Windows Phone 7 apps. Windows 10 Mobile phones couldn't run Windows Phone 8 apps. Windows RT tablets couldn't run any x86 apps. Windows on ARM laptops can't run 64-bit x86 apps, only 32-bit (which is funny, given that it seemed for many years that 32-bit was going away).
