I think these kinds of devices are for different audiences.
GrapheneOS would probably best suit people that don’t trust the software on their device, but completely trust the hardware.
The Murena or a Pinephone with hardware switches would be ideal for someone who trusts the software, but wants the ability to control the hardware.
Practically, this appeals to people who are considering things like Qualcomm’s GPS in some SoCs bypassing the OS to request almanac data, using the cellular modem directly IIRC (gets worse: unencrypted http and includes your IMEI in plaintext). This doesn’t happen in Pixel devices because there it is handled in software entirely, and of course those don’t use a Qualcomm SoC
