I call pluggable IPI whacky, and it's not outragous. What is outragous is your bullshit architecture astronaut patches. There might be a nned to abstract IPI details even more in the future, but the way to do it is either architectureally in the RISC-V privileged spec, or in the SBI spec once we actually have one. Having host OSes go through hoops to provide pluggable IPI implementations is complete bullshit, and the argument that we already have this in some architectures is not a good reason to repeat that mistake.
