That's not a reason. When the hardware doesn't have those "security features", then don't "really secure", just run without being "really secure".
I never treat my (Android) phone as secure anyway.
Security is GrapheneOS's raison d'être. If you don't want security, you can run another Android build that does run on the hardware you have.
