Someone might also file a new parent, then apply it against RISC-V. You'd think that wouldn't be allowed to happen, and maybe it isn't, but only an expensive lawsuit will prove it

Given the nature of the US legal system as based on common law, that applies beyond patents, and may affect ARM and x86 as well. In the end, the real, effective law is the one understood by judges, adjucated in court cases, built on precedents.
That being said, I don't expect someone filing a new patent after a RISC-V extension being published to last much longer beyond discovery in most cases, which should keep costs in lower end. Specially so in cases of bad faith.
