So, is it assumed as a bug more than a removed feature? If this is a bug and could be fixed I would treat this different to "no more support for older macOSes".

In this case, it's an unintentional bug.

How do you know? Maybe it's in the mentioned bug report 15774587; I tried to look at it, and was sure I could log into Radar at some point, but now I can't seem to dig up any valid login.

Based on the virtualization framework documentation, this seems very intentional.

My guess is that they do this because their development processes only assure that the macOS version shipped with the hardware works on that hardware. And the virtualization layer is really thin.

They see no reason to spend the extra QA time, but rather have everyone upgrade to the latest macOS version their hw support.

Do you think it could be simple to fix, even by a hackish third party?

Unless you work at Apple, none of us outsiders have even been able to look up other people's bug reports

Are you sure? I'm pretty sure that I have in the past, and even that it used to be standard practice when discussing an ignored Radar report to ask other sufferers to go to the bug and do whatever the "me too" action for Radar is (I don't remember). Certainly there is a login at https://radar.apple.com, although that doesn't prove that it's meant for outsiders.
