Removing old kernels doesn't clean up

[actionparsnip]

I noticed that the removal of old kernels does not uninstall the kernel headers for that kernel, nor does it delete the folder in /lib/modules

Linux-headers are at about 130Mb i memory serves, this could cause a lot of bloat if a lot of kernels have been installed (through regular updates). Even if the kernel is removed to save space, the headers still remain. Is this intentional?
