People are allowed to have opinions on how much visual indentation they want in their code. When I first started coding I found 4-space indentation to be really helpful when I would easily get lost in my code. After a few years I preferred 2-spaces. So there is an argument to be made about accessibility.

People have debated endlessly about tabs vs spaces, and ultimately most of people's opinions are just a bit silly. There is only one consequential difference between the two:

Tabs allow individuals in the same codebase to select their indentation widths across every tool (yes including GitHub using either the .editorconfig or a user-style with tab-size), and spaces do not (at least not across every tool).

As such, I think we should switch to hard tabs for everything in Rome.

I'm gonna make a request that people refrain from flooding this thread with subjective opinions about if 2-space width code is better than 4-space width code. You are welcome to have your personal preference, that is the entire reason for choosing hard tabs.
