Why not `home.file.<name>.text`?

In Chapter 6, you noted that

	Before we start, I want to make something clear: in the long run, you actually
	probably won't use this very often. You'll want to prefer using specific
	configuration options that will generate config files, or using other
	functionality to build shell scripts, etc. However, it's very easy to get
	started with this, and it can be useful for sketching out some ideas or just
	getting a file somewhere that you want it. Mostly it's a great excuse to show
	you some more new syntax.

	_Again, this is NOT actually the long term solution you want for writing your
	own utility scripts. The long term solution you want is probably
	[`writeShellApplication`](https://ryantm.github.io/nixpkgs/builders/trivial-builders/#trivial-builder-writeShellApplication)
	in nixpkgs, which is available in `pkgs.writeShellApplication`. This requires
	some significant extra work and understanding, so bookmark this later and return
	to it once you're more comfortable with Nix generally. If you want a taste of
	what this might look like, [here's what I do to generate a bunch of helpful
	wrapper scripts in my own setup](https://github.com/Evertras/nix-systems/blob/main/home/modules/shell/funcs/default.nix)._

But why? Sure, using modules like https://github.com/nix-community/nixvim is more "elegant" than copying and pasting ~/.config/nvim/init.lua from an existing system, but the latter is at least as expressive as the former, and requires essentially zero effort. Is there any practical advantage besides aesthetics?
