The C++ situation was completely different, Linus said from the get go "no way", thus nobody put serious work writing c++ code for the kernel. With Rust Linus essentially said let's see how it goes, but specifically said he would deal with maintainers who would be unwilling to consider code that would be necessary for R4L. Based on this people invested significant work into writing code that is quite widely used, only to now have a maintainer saying he'll oppose any Rust code coming into the kernel, and Linus saying the guys trying to get the code in are the problem.
