My point is not an universal IR that can compile every C program ever written, rather an IR that is compliant wiht the abstract C machine as defined by ISO C, and that has been done multiple times.

Right, sure, we don't disagree. Strictly speaking, what you've described is trivial:

1. Fork the RISC-V ISA, but brand it as an IR rather than as an ISA intended for hardware implementation

2. Port a C compiler to target your new ISA

3. Port QEMU to execute your new ISA

There you go, you can now compile C to your novel representation, and you can use QEMU to run C programs that have been compiled to it.
