I know very well about Zerodium. However, FPGAs can be way more secure than any kind of ASICs. If you don't understand why, then I don't think further discussion is warranted. I worked with Apple's implementation of security enclaves, and they don't isolate (or "outsource" to be processed there) nearly as much as should be isolated. For example, whole display and touch input needs to go through the application processor, anyway. It's not a good way to go, to say the least. You can't overlay anything on the top of the display nor isolate touch input from some area (say, virtual keyboard) to go to the enclave. The rest of what it does is pretty meaningless, given these constraints.
Ah, you mean social engineering attacks and more powerful attacks relying completely outside of the cyberspace (to say more bluntly, which perfectly fits the case here, "in the meatspace"), right?
In terms of broadly-understood virtualization, there's always FPGA with its possibility to spawn multiple number of completely independent softcores. These days some FPGAs with enough computing power for well-optimized security-critical part of general-purpose computing (messaging, web browsing, maybe DSP - not computation like neural models) have fully open-source bitstream synthesis tools.
BTW, thanks a ton for letting me know about the unpatched vulnerability in Alpine. I'll talk to the pmOS guys about patching it.
My phone doesn't run Xen yet (I've ran into some problems with kexec() support in Linux on aarch64), but it runs KVM just fine ;)
However, it seems that in Debian it's patched https://security-tracker.debian.org/tracker/CVE-2015-0235 . Is what you're talking about Alpine-specific?
Anyway, Alpine seem to use musl instead of glibc.

"A modified version of OpenHaystack to showcase the possibility of building a stealth AirTag clone that bypasses all of Apple's tracking protection features."
Other projects from them, like https://github.com/positive-security/send-my , also seem interesting.
I absolutely agree with the rest, though, including the part saying any "serious" software will have such features (and better support in general), and I second the examples you gave.
