dracut call during kernel uninstalling
If I uninstall an openSUSE kernel, why does the RPM scripts call dracut? I don't think, this is useful. Probably it has something to do with the fact, that one kernel has three RPMs (kernel-default-5.14.21-150400.24.55.3, kernel-default-extra-5.14.21-150400.24.55.3, kernel-default-optional-5.14.21-150400.24.55.3 in the example). An example (openSUSE Leap 15.4): mybox:~ # rpm -qf /boot/vmlinuz-* kernel-default-5.14.21-150400.22.1.x86_64 kernel-default-5.14.21-150400.24.55.3.x86_64 kernel-default-5.14.21-150400.24.60.1.x86_64 mybox:~ # zypper rm kernel-default-5.14.21-150400.24.55.3.x86_64 Reading installed packages... Resolving package dependencies... The following 3 packages are going to be REMOVED: kernel-default-5.14.21-150400.24.55.3 kernel-default-extra-5.14.21-150400.24.55.3 kernel-default-optional-5.14.21-150400.24.55.3 3 packages to remove. After the operation, 232,5 MiB will be freed. Continue? [y/n/v/...? shows all options] (y): dracut: Executing: /usr/bin/dracut -f /boot/initrd-5.14.21-150400.24.55-default 5.14.21-150400.24.55-default dracut: dracut module 'systemd-coredump' will not be installed, because command 'coredumpctl' could not be found!

I suspect this very good question would get better response on the factory mailing list, but probably someone with a blazingly fast computer is the upstream dracut developer, and he/she/it hasn't bothered to deal with the waste these calls cause. cf. https://bugzilla.opensuse.org/show_bug.cgi?id=1192014 provide admin option to NOT automatically REbuild initrds for previously installed kernels which if fixed could mitigate the waste. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

Because you remove package(s) with additional kernel modules and dracut is called by these packages (they may remove modules that were included in initrd).
An example (openSUSE Leap 15.4):
mybox:~ # rpm -qf /boot/vmlinuz-* kernel-default-5.14.21-150400.22.1.x86_64 kernel-default-5.14.21-150400.24.55.3.x86_64 kernel-default-5.14.21-150400.24.60.1.x86_64
