I don't really care about code styles, all projects I had to decide about, had a code style guidelines that basically said: "Make it good to read, we will discuss what that means later" as guideline. I do get that this only works for small teams.
What I would like to have, however, is two sets of formating rules: On-Disk and In-Editor. I will only ever see my in-editor form. I do not care about the on-disk form.
(In my mind, I hear IDE developers crying out: "How should we map compiler/debugger code positions?!?" … )
