I feel this way chiefly because I actually do use the features of NixOS to atomically rollback entire machines in production, and to atomically upgrade my development workstation. Having to manage an additional piece which is beyond Nix, whether that's EFI configuration or virtualization or Bedrock, is acceptable but very irritating.

Apologies, I misinterpreted your concern to be a matter of losing the entirety of Nix's atomic features entirely rather than concern over even limited escapes from its Nix's scope. In this case it does sound like Bedrock's trade-offs won't be worthwhile for you even in the hypothetical future where it plays nicely with NixOS but retains the non-atomic nature of components from other distros.
