if i use btrfs subvolumes, does it mean that i can have one EFI partition and one root partition, and then subdivide the root partition using subvolumes?
Yes.
how would that work during the installation process? or is it done after installation?
That depends on your distro. What do you plan to achieve with the separate subvolumes?

What's with all these hip filesystems and how are they different?
You know, ZFS, ButterFS (btrfs…its actually “better” right?), and I’m sure more....
