While I supported that idea of Rust coreutils, this your experiment showed me how bad it is. My results are totally different, but not what I expected (edited out long strings of "a/a/a" for brevity). I wouldn't call it stable...

  root@71a8c5a6c5e3:/# mkdir -p $(yes a/ | head -n $((32 * 1024)) | tr -d '\n')
  mkdir: File name too long
  root@71a8c5a6c5e3:/# gnumkdir -p $(yes a/ | head -n $((32 * 1024)) | tr -d '\n')
  gnumkdir: cannot create directory 'a/a/a/.../a/a': File name too long
  root@71a8c5a6c5e3:/# gnumkdir -p $(yes a/ | head -n $((3 * 1024)) | tr -d '\n')
  root@71a8c5a6c5e3:/# rm -rf a
  rm: cannot remove 'a/a/a/.../a/a/a': Directory not empty
  root@71a8c5a6c5e3:/# gnurm -rf a
  root@71a8c5a6c5e3:/# rm -rf a
  root@71a8c5a6c5e3:/#

And then they plan to move to a new Rust-based NTP. No comment...
