This patch forces loading of the btrfs module for everyone, and the
inclusion of the "btrfs" tool in everyone's initrd.

Perhaps you can just use boot.initrd.kernelModules and include btrfs there?
Normally, it seems nixos' initrd builder detects the filesystem type
that / is on and includes the needed filesystem module in the initrd.

I've been running with btrfs for some time and I didn't need to do
anything special. However, that was a single disk configuration
(laptop) so I didn't need "btrfs scan" or force module loading, or
even set the fsType in the fileSystems array.

Can you make these 2 lines (modprobe / scan) optional, depending on
any filesystem having an explicit "btrfs" fsType in configuration.nix
?
Then you just need to flag that if you are running a multi-disk btrfs
configuration.
