The argument to "bash -c" is a single-qouted string though, so the shell
would not expand the variable.
On my Alpine system (bash 5.3.37), LC_NUMERIC is unset, and setting
LC_ALL does not automagically set LC_NUMERIC in "bash -c":
% LC_ALL=C bash -c 'echo "$LC_NUMERIC"'
(blank line output)
% LANG=C bash -c 'echo "$LC_NUMERIC"'
(blank line output)
