They have to prioritize and worry about the overall complexity added by a feature against the benefit provided by that feature. So there are two ways that I see a feature getting into any tool, clang-format or otherwise:</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">1) Someone presents a compelling use case that motivates the author / maintainer of the tool to accept a patch (or even author a patch) which adds the desired functionality. An example of such a use case for this would be: huge open source project XYZ won't be able to use this tool without it, but with it they would benefit hugely and some might start using or even contributing to clang. This isn't a hypothetical: we added support for the Linux kernel's coding styles.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">2) Someone works really hard to send high quality patches to the tool, or even to other tools and other parts of clang. They demonstrate that they are a committed long-term developer on the project. Then they request that they be allowed to add the feature and they take on the increased maintenance burden attached to it.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra"><br></div><div class="gmail_extra">I have looked at a decent amount of C++ code in various open source projects and talked to a decent number of C++ developers and I have heard roughly one of them (you Ben) advocate strongly for this style as a good and useful thing they would like to continue to use in their codebase while they are using clang-format. That's not enough for #1 even for a very simple feature. I think we would need to see *some* evidence of the size of developer community that would benefit from the feature, and that this size is not in the small 10s of people.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">The second path is clearly always an option, although it is often a challenging route to take. FWIW, I *always* hope people take path #2: it means the Clang community grows! It's the path that I took myself, that Manuel, Edwin, Richard, and many other core contributors to Clang and Clang-based tools took. It's a great path if you can take it, but it is an expensive path.</div>
