That makes sense.
Ok, I think it is better to keep the older kernel because I do need some

One time about 12 years ago I had a kernel update that had a bug which
prevented me connecting to the modem, I was able to reboot to the previous
kernel & continue as before. I raised a bug report, & the next kernel I
downloaded had that bug fixed.
So Yes, it is good to keep a few previous kernels around just in case ...
