Blocking DMA is separate from 0days. One is a design decision, the other is a still-unavoidable consequence of complicated software.
I think that these mechanisms completely frustrate "bulk" in-field collection efforts; for example, scanning all phones at DUI checkpoints.
No technical control is perfect. If you personally piss off a nation state adversary, they are more likely to yeet you off to a black site and hit you with a wrench until you cough up your passcode.
Surely, someone will break iBoot, and surely, someone will break SEPOS. And surely, someone will chain a kernel exploit with a userspace exploit [0]. And surely, someone will leak the signing keys for a widely deployed cheap android phone [1]. And surely, someone will push 777 permissions to a cloud provider [2]. And most surely, powerful government adversaries will hold brutal exploits close to their chest in the service of power and politics [3].
So I guess, if you want to breath freely: host your infrastructure yourself where feasible. Choose providers who respect your privacy. Make a modest but financially fair donation to the EFF. Become politically active. Use better practices - not best - to avoid fatiguing yourself in the windmill chasing effort of being Perfectly Secure. Most importantly, stay awake and aware and ready to fight.
