I just had the same problem on linux-image-6.6.15-amd64.

TBH, I'd even argue plain "remove" should remove the debris from the
modules directory, it's not like there's anything of value in the
modules.* files left behind.

Kernels are the only package that I'm actually purging, if "remove"
wouldn't leave /lib/modules/*/ behind, I wouldn't have to do that.
