Thanks for noticing :)
Note coreutils also got a new ./configure --enable-single-binary
option recently to build all tools to a single binary like busybox.
The tradeoff is somewhat higher startup cost, and RAM cost,
due to all shared libs being linked. Chromium is using this
build configuration I understand.
