Doesn't need to be security related at all, where will you get the drivers for your hackintosh ARM GPU, Network, Bluetooth, etc. With Intel Apple was using standard off the shelf components, with ARM it's all proprietary and baked in to their SoC - why would they write support for any other SoC ? Not to mention they will probably include proprietary chip specific stuff and assume it's there which will not be present on other devices.

The community --- providing it still exists --- will write them... or at least some of them. When I was playing around with Hackintosh many years ago (when they were still 32-bit), I took the lack of drivers as a motivation to learn how to write some. Of course, the PC legacy really helped with things like BIOS and related standards, so ARM will definitely have a much steeper curve.

(The diversity of ARM platforms in general put me off writing code for them --- it feels like a losing battle when there are so many platforms, especially when most of then are unlikely to even exist for much time. The fact that it is the same CPU core matters little when everything else is different. Maybe it is the same for many others.)

How long did it take for opensource drivers for stuff like Ras Pi GPU ? On the flipside is there any support for recent nvidia cards in hackintosh ?

I seriously doubt the effort required to write a functional GPU driver is going to come from OSS for something as fringe as Hackintosh on a random ARM SoC, like you said they get replaced constantly and the landscape is fragmented.
