The complexity of kernel isn't relevant, unless your point is that the kernel is already so complex that maintainers shouldn't advocate against new and significant complexity?

As for less work, that is alternative two from my original post which states the maintainer now has to wait for someone else to do the work or risk his change being stalled (worse case: indefinitely). It doesn't matter if the R4L team promises that they are OK with broken Rust code since the only person whose decision matters is Linus. Until Linus clarifies his stance on broken Rust builds the promises of the R4L team are promises that they are literally incapable of delivering on.
