Mozilla, WebKit, LLVM and Microsoft. They have their style distributed
with the official clang-format, not sure if they enforce it.

Same for Chromium/Chrome, but it looks like they indeed enforce it:

"A checkout should give you clang-format to automatically format C++
code. By policy, Clang's formatting of code should always be accepted
in code reviews."

I would bet other Google projects do so as well (since Chandler
Carruth has been giving talks about clang-format for 7+ years). Nick?

I hope those are major enough. There is also precedent in other
languages (e.g. Java, C#, Rust).

It would be good to see particularly bad snippets to see if we can do
something about them (and, if needed, try to improve clang-format to
support whatever we need).

Did you tweak the parameters with the new ones? I am preparing an RFC
patch for an updated .clang-format configuration that improves quite a
bit the results w.r.t. to the current one (and allows for some leeway
on the developer's side, which helps prevent some cases too).

I am thinking about special tables that are hand-crafted or very
complex macros. For those, yes, I think it is a fine solution. That is
why clang-format has that feature to begin with, and you can see an
example in Mozilla's style guide which points here:

Cheers,
