Does Docker abstract filesystem behaviors like this? I always thought that it stopped at the libc level - that is, libc is included in the container, but it calls the host kernel's system calls, and so inherits the host kernel's behavior (including things like underlying filesystem case sensitivity).
Docker relies on LXC, so it's Linux-only. On other platforms it runs in a Linux VM. The host for Docker, then, is Linux no matter where you are.

Docker hasn't supported LXC since 2016, and stopped relying on it in 2014

I thought the name for the collection of kernel features was LXC, I didn't realize (until just now) that was the name only for the also-kernel-level wrapper for those features, which name does not cover the features themselves. That is, I didn't realize that LXC is to Cgroups+Namespaces as Libvirt is to KVM—I thought LXC, as a label, covered the whole feature-set—but regardless, it's still married to Linux kernel features and runs on other platforms under virtualization, no?
