They probably should have the option to change the tab size on an open file, but my point is, why wouldn't you have autoformatting on for YAML and JSON? You have a preference for indent size, and you want the same for every file, barring an edge case.
Edit: Yeah I see your point when you are not in control of the project and have to stick to someone elses style, I guess that only seems like an edge case to me, but could be normal for other people. In that case you would want a convenient way to override your formatting settings, like an auto detect indent button that only applies to the current open file.
To me it basically seems backwards. Of course I am not arguing against having a robust configuration for setting indentation settings, it's usually the ideal way to handle this sort of thing. However, it's ultimately still just a convenience feature; all you really need is the ability to set the indentation settings for the current buffer.
As far as editors that have automatic indentation features, Zed is definitely the first one I can think of where it had configuration for indentation settings per project/per language, but no ability to change it for the current buffer.
I'm sure in due time, it will probably gain most of these features as more people jump in and run into these problems.
