Apparently, the convention (at least starting from 2018) is to make the keywords and block names to be in lowercase as stated from one of the following discussions at https://orgmode.org/list/87tuuw3n15.fsf@nicolasgoaziou.fr/. The files was updated with a one liner of shell. However, this is Emacs and org-mode does have an API to let you do stuff in your config and interact with the documents internally so it is not an elegant solution in any way.

Nix package manager
Nix is a package manager that pioneered Functional package management which addresses the criticisms of traditional Unix systems while making it as a specialized tool for Reproducible research. Holistically, Nix is made up of at least four components: the store, the language, the derivations, and the sandbox.
- The store is a immutable centralized location where all of the outputs are placed.
- The derivations are essentially build instructions.
- The language (also called as Nix but we'll refer to it as Nixlang) is a domain-specific language for creating derivations.
- The build process can be locked in a sandbox, improving the reproducibility of a setup and lowering the attack surface for a malicious package.
Furthermore, it also offers one of the must-haves as a power user (in my opinion) which is declarative configuration. You can write the whole system configuration in a plain-text file giving you all of the little knobs and switches of the system. Even then, it also applies some abstraction if you don't want the full control which is an attractive option if you're looking for a quick setup. Finally, they are suitable to be used under a version control system like Git and Subversion giving more room for experimentation 1 and control.
As if the rollback feature for NixOS wasn't enough.
