ic, this probably explains why it's used sparingly so far. Thanks for the explanation. I'll try to educate myself on this wrt enabling this for modload.

We use weak symbols all over the place in user space.  It's just that the kernel-resident linker doesn't support them (yet?), so we can't use them for symbols that are part of the ABI exposed to modules.

The other option for me is a bunch of ugly #ifdefs , which I'm trying to minimise.

Reducing #ifdefs is a laudable goal.
