Although I would prefer to use PCRE (-P) for consistency, IIRC it is not fully supported across all distros/versions, so I am fine with using -E here for now.

Unfortunately -P does not appear supported on macOS grep:

% grep -P
grep: invalid option -- P
usage: grep [-abcdDEFGHhIiJLlMmnOopqRSsUVvwXxZz] [-A num] [-B num] [-C[num]]
        [-e pattern] [-f file] [--binary-files=value] [--color=when]
        [--context[=num]] [--directories=action] [--label] [--line-buffered]
        [--null] [pattern] [file ...]

)
