nixos-options and helm-nixos-options load slowly

I haven't looked into why, but these two are by far the slowest loading pkgs in my spacemacs:
3.4 and 4.0 seconds, with the runners up needing 0.6 and 0.5 seconds.

It also blocks the execution of my editor when opening nix files. Is it possible to run nix-build asynchronously?

I asked doom-emacs to remove this package because this bug.

Thanks.
I use doom as well now.
It'd be nice if the root cause was found though.

Well. I know the root cause, the module should use the non-blocking api for executing nix-build. But my emacs-fu is not strong enough to make this happen. This is a similar problem to: wbolster/emacs-direnv#31

Also see purcell/envrc#6 for more discussion on making things asynchronous.
