I suspect that just like systemd has container and virtual machine
management support, it is now adding btrfs volume and snapshot management
support (some of which might even be useful in conjunction with containers
or virtual machines).

It does seem like trying to tie too many things together.

Had you noticed there is a machined virtual machine manager in systemd?
I only noticed that recently.  And of course machinectl to go with it.
You can even do systemctl -M vmname command, to run systemctl command
inside that named vm.  I suppose that could be convinient.
