If Microsoft really wanted to, they could find a way to squeeze the old panels into the new UI. They can run x86 binaries on ARM, and all sorts of other tricks, its not like they lack the engineering talent.
They also do loads of shims/special treatments for specific apps based on a compatibility database. Worst case scenario, they could rewrite the top ~100 most common ones and make “Legacy Control Panel” an optional feature that is off by default.
It has been 5+ years since Windows 10 came out, longer since 8, Microsoft really doesn’t need people making excuses for them.
