No, they don't support it. Instead, you need to run it inside a compatibility mode, that probably sandbox or VMs the facade. But your software keeps running.
The current problem is that your software no longer runs. That's a 100% denial of service problem.
> I want to run a modern OS with modern features and still run any software that I already paid for 5, 10, 20 years ago.
I already have a bunch of software that I paid for more that 20 years ago and I can't use most of it outside of full VMs. Microsoft didn't ask me if I didn't use them anymore before removing Win16 support.
> Out of curiosity, have you asked customers to run your software in a VM? How did that conversation go?
Customers never got a choice "where to run your software" when all software I develop ends up hidden inside a SaaS service or being delivered via representational state transfer code on demand. They either run it on a browser sandbox or it doesn't run.
So 10 years from now, all popular distros should support versions of Facade 1.0, 1.2, 1.42 through Facade 10.2?
Now do you see the problem?
