Oh, then only warn when set +o posix and shopt -u
compat_im_too_lazy_to_fix_backticks is in effect!

Seriously though, the internet is awash with "helpful" Shell guides and
examples loaded with poor practices. The only way this is going to improve
is if there's a "linting mode" is included in the Shell and on by default.

Consider this a feature request for a linting mode, on when invoked with
bash -n or bash6.
