I've tried that now, and it works pretty nicely for me.  Apple clang 
version 14.0.3 (clang-1403.0.22.14.1)

I now have

export CLANGD_FLAGS="--limit-results=1000 --limit-references=1000"

in my .zshenv, and I'm using exec-path-from-shell in Emacs to get
that setting into Emacs on macOS.

Also, and completely unrelatad, I found that one can add a .clangd, 
which made post-processing the compile_commands.json generated by bear 
unneccessary.

Put a .clangd in the toplevel directory of the Emacs tree with contents

---
If:
    PathMatch: "src/.*\.c"
CompileFlags:
    Add: [-include=config.h]

(Not sure if that first line is obligatory.  I'm not a YAML user.)
