Similar to this question although about a different edit
The help page on editing lists these as the most common reasons to edit a post:
- To fix grammar and spelling mistakes
- To clarify the meaning of the post (without changing that meaning)
- To include additional information only found in comments, so all of the information relevant to the post is contained in one place
- To correct minor mistakes or add updates as the post ages
- To add related resources or hyperlinks
No help page goes in-depth about what formatting should warrant edits. Common sense would suggest that if the whole post is capitalized, bolded, in italics, etc. there is reason to edit - or that if there is a giant wall of text there may be reason to add headers, or blockquotes, or bullets.
I think too much of anything is a reason to edit a post, but that just as bold, italics, etc can make headers or show emphasis, so too can TeX editing. It may not be the intended use, but that does not make it "incorrect". See this post of mine, for example - I believe using TeX formatting to show emphasis is not "wrong", just "different" and that there is no reason to edit it out.
Is it justifiable to edit TeX out of a post just because it is being used to show emphasis in a different way, as opposed to mathematics?
