I think keeping the other kernels is a plus. I use the proprietary nvidia driver (nvidia repo) and
also the latest kernel (Kernel:stable:standard). Sometimes the nvidia driver does not work with a
new kernel. When this happens, I use yast (in console as there is no X) and uninstall the newest
kernel. Eventually nvidia releases a new driver, then I can use the newest kernel.

I just remove older kernels when I know I won't need them as a fallback any longer.

In the past, I would loose the newer kernels when a new one was released. Then I  would have to go
back to the default kernel for the version of openSUSE at the time. Accumulating them allows me to
fallback to a newer kernel when it is no longer available in Kernel:stable:standard.

BTW, thanks for mentioning purge-kernels.service. I didn't know about it. It was enabled on my
system but inactive. I've disabled it now.

This is just my use case and my 2 cents.

Cheers,

Alvin
