Take a look at the past 3 years of presentations at DARPA ERI, where every major US silicon vendor is participating. Much work is underway on heterogeneous systems, including Open FPGAs and OSS toolchains for EDA, to speed up (days, not months) the design-test-deploy cycle for specific applications.

AMD provided a custom (expensive) SoC and RoT to MS Xbox, now being generalized with MS Pluton in 2022 Ryzen CPUs (and some future Intel CPUs). Intel already offers custom CPUs to some large customers. If a security-sensitive automotive or robotics customer needed an FPGA RoT, and the market opportunity was sufficiently interesting, Intel has multiple options for meeting that requirement.

Intel at least left open the possibility in their press announcement. AMD did not, but they have purchased Xilinx and TSMC is building a US-based fab in Arizona, with "secure supply chain" FPGAs high on the list of early product candidates. It's up to customers to bang on Intel/AMD doors and show demand for FPGA RoT chiplets that support OSS gateware.
