I think what you're advocating for is getting rid of automatic dynamic loading, which is certainly a take.

What does "pure" ELF64 even mean? No dependency on libc?

ELF is just an object file format. It doesn't imply anything about how the loader behaves or what features an ELF loader must have, or how that object relates to other ELF objects.

Yep, services from the libc would be libdl-ed too. You would have to decide: either you use the machine code in a shared object, or you would statically link that machine code, but the idea is to make those explicit and different, not that current mess.

It means using the sysv x86_64 ABI entry point (which is basically a main()...).

The file format alone is useless, you need the ELF and ABI specs to know how to use properly the information defined by this very file format.
