Here, you are wrong.
Those installed files should be removed by %ghost markers.
I already have a local patch to do this.
(see the attachment)
I just asked you to fix up the code as I suggested in v4.

For me (on Fedora 39 and openSUSE Tumbleweed), rpm fails due to file conflict.
vagrant@opensuse-tumbleweed20231218:~> sudo rpm -i
kernel-6.7.0_12924_g660a5f4a53e7-4.x86_64.rpm
file /lib/modules/6.7.0-12924-g660a5f4a53e7/vmlinuz from install of
kernel-6.7.0_12924_g660a5f4a53e7-4.x86_64 conflicts with file from
package kernel-6.7.0_12924_g660a5f4a53e7-3.x86_64
So, this does not happen.

No. Please do not.

Subject: [PATCH] kbuild: rpm-pkg: specify more files as %ghost
Installing the kernel package is fine, but when uninstalling it, the
following warnings are shown:
warning: file modules.symbols.bin: remove failed: No such file or directory
warning: file modules.symbols: remove failed: No such file or directory
warning: file modules.softdep: remove failed: No such file or directory
warning: file modules.devname: remove failed: No such file or directory
warning: file modules.dep.bin: remove failed: No such file or directory
warning: file modules.dep: remove failed: No such file or directory
warning: file modules.builtin.bin: remove failed: No such file or directory
warning: file modules.builtin.alias.bin: remove failed: No such file or directory
warning: file modules.alias.bin: remove failed: No such file or directory
warning: file modules.alias: remove failed: No such file or directory
The %preun scriptlet runs 'kernel-install remove', which in turn invokes
/usr/lib/kernel/install.d/50-depmod.install to remove those files before
the actual package removal.
Modern RPM-based distributions do not ship files generated by depmod.
Mark them as %ghost in order to exclude them from the package, but still
claim the ownership on them. Do likewise for the files copied to /boot.
