All good until here.  (Maybe the glibc commit that removed this
could go in the commit message, if you know it.)

I don't know it, unfortunately.

Did this change with glibc 2.34?

The glibc manual changed (it started documenting this stuff) but this
part of the implementation did not change.

The documentation is somewhat older than 2.34 and was just minimally
amended.  It's here:

  Replacing malloc
  <https://www.gnu.org/software/libc/manual/html_node/Replacing-malloc.html>

In particular, it lists additional functions that may have to be
interposed due to application use.

Thanks,
