Correct, as otherwise user 200 could change the kernel and do all sorts
of bad stuff (like make a kernel which lets user 200 have root access...).
On a mono-user home machine, it probably doesn't matter.

I bet this is one of the GENERIC distributed kernels. If you looked on
the machine which compiled the kernel, though, you would find a user
200. :-)
