Hackintosh community has some of the extraordinarily talented developers, who has over the years developed sophisticated tools and methodologies to run vanilla macOS on non Apple hardware[1] or on AMD CPU with custom kernel.
Apple so far hasn't explicitly indulged in sabotaging hackintosh scene(Only those who sold pre-built hackintosh hardware incurred Apple's wrath), in-fact some hackintosh specific kexts where whitelisted officially in the macOS few iterations back when kext signing became mandatory.
Apple's blind eye towards hackintosh made sense as besides increasing penetration for macOS, it provided access to iOS app development in markets where price of Apple hardware was the primary barrier to entry unlike Android development.
But, interest for hackintosh seems to be declining steadily[2] since it's peak in 2008(snow leopard 64bit?); may be because tools for hackintosh are very stable now, macOS hasn't undergone major architectural change until now (or) is it economic uptrend around the world which makes entry level MacBook a promising investment for iOS development.
Anyways, things have changed today; macOS Big Sur is the official transition of macOS to iOS with better mouse and keyboard support. Would apple lockdown MacBooks further to the level of iPhone/iPad that, macOS upgrades wouldn't be available as separate package on Mac AppStore? I don't see a reason why it wouldn't in the future.
macOS upgrades available as a separate downloadable package is crucial for hackintosh, without it accessing macOS would amount to piracy.
Would this rekindle the hackintosh development to support other ARM hardware(RPi 6?) for macOS or will Apple doubling down on lockdown kill the hackintosh scene for good in this decade.

The idea that “Macs” will be relatively generic x86-64 machines made by a specific company to run its OS preferentially is gone. Macs’ inner workings will go back to being comparatively exotic, as they were in the PowerPC days and before: incompatible with the prevailing wintel hegemony, which for Apple has the pleasant side-effect relieving them of many competitive forces (but I digress).
In future getting macOS to run on non-Apple hardware will be far more difficult. The Ax series SoCs are ARM-based but contain loads of Apple-specific implementations and additions. Think of the T2 chips and the Secure Enclave. Those won’t be turning up on commodity silicon before the relevant patents expire!
Look at it the opposite way: how successful, really, have efforts to get Linux running on Apple’s iPad, iPhone, and AppleTV platforms been? Why? Because it’s undocumented. That’s what ARM macs will be like in the future.
