I don't think I ever manually removed them, so it was likely removed by an automated upgrade / autoremove at some point.

You may be able to discover how this happened by zgrepping
linux-headers-amd64 in /var/log/apt/history.log* and
examining any files that match.

Here's where I upgraded the kernel the other day, and autoremoved
the third (and oldest) version. Obviously I didn't remove
linux-image-amd64, which by analogy with linux-headers-amd64,
keeps the kernel itself up-to-date. (This machine doesn't
currently require kernel headers.)
