Not sure this is 100% relevant to the discussion, but -Q also implies
--no-site-file which inhibits site-start.el. This will interfere with Emacs
builds such as https://github.com/jimeh/emacs-builds for macOS. They
rely on site-start to establish bundled native compiler runtime
dependencies. Running a flymake batch without those dependencies may have
unintended flymake performance implications.
