Each ELF library declares the symbol versions it provides. The dynamic linker could track which library declares which versions, and cross reference that when it looks symbols up. I though it did, but from empirical testing, it doesn't. But if it did, it would get similar speed improvements, assuming all libraries provide at least one version each (and of course, assuming no overlaps).

That's what "direct binding" is. And as you can see, Linux doesn't support it.
