Get ready to not have root access on your laptop. The writing is on the wall:

  * signed software restrictions 
  * no kernel extensions
  * SIP

Dropping x86 compatibility will be the last nail in the coffin. Buy the x86 platform if you value your freedom, buy arm if you want a larger form factor smartphone

There's no evidence for this. They could remove root access now on x86 if they wanted to. They didn't have to spend engineering hours making it possible to disable SIP when they turned it on. Most software signature restrictions that have been added to macOS to date are easily disabled, and besides that have nothing to do with x86 vs ARM.
