basically no non-trivial modules will work with this on, and users are dumb and don't read Kconfig descriptions.

+1 on adding this check. I have just tried to install nvidia-drivers on a system on which I had previously enabled TRIM_UNUSED_KSYMS in the kernel and it failed spectacularly, with both build-time errors (which I managed to work around) and nvidia.ko not loading due to undefined symbols. Fortunately I remembered there being such an option in the kernel config so I was able to fix it.
