I'm not sure I've seen linker scripts used outside of glibc and libz? What are they used for these days?

Anything targeting bare-metal hardware, for one.

FWIW, I've used one a couple of years ago to create some symbols within a static struct to preserve ABI compatibility in a library while doing a massive overhaul of it.
I haven't tried it but maybe if you want to embed a payload directly in an ELF section for $reasons ?

I seem to remember a project called "Linnucks" or something that relies linker scripts? I think it's an OS kernel (just a hobby, not big and professional like GNU).

Maybe it's possible but for any sort of low-level stuff I think I've always had a linker script.

Still, you could probably identify a fairly small subset of the linker script features that would be able to build most projects? But I dunno.
