Why wouldn't it? Compiling spawns lots of processes and that kind of thing usually involves printing the PID when logging what you are doing to be able to distinguish between different instances of the same program (e.g. the compiler when spawned by some sort of build tool).

Then the tools that spawn such processes, if they want to implement tracking by pidfd, will need to implement appropriate fallbacks (which are easy to add as the error codes are different). They'll need that anyway for compatibility with older kernels. So still not sure where the regression would be?
