Presumably, they are on https://opensource.apple.com/source/bash/bash-118.40.2/ although sources for the latest macOS are usually not released in a timely manner (no Big Sur at the moment, for instance)

rootless.h has never been made available to the public as far as I know.

I just found that the new dump of sources for 11.0.1 has a version of bash that doesn't #include <rootless.h>

[cozzyd]

that's odd... what does Apple have to win out of a GPL violation for this?

[saagarjha]

Nobody has forced them to release it, so until then they get to keep some magic to themselves, presumably.
