I'm actually wondering if it's worth working on flycheck at all at the moment.
reading this post: https://www.masteringemacs.org/article/spotlight-flycheck-a-flymake-replacement I found this: > So why switch away from Flymake?

We're not "using an older version of Emacs", we're pretty good at keeping up with upstream releases. So why should we bother with Flycheck? There's a comparison page that still seem to favor flycheck; https://www.flycheck.org/en/latest/user/flycheck-versus-flymake.html ... but it hasn't been updated in 3 years, so I asked upstream for an update: https://github.com/flycheck/flycheck/issues/2023 I might also try to switch back to plain flymake myself. a. -- There is no power on earth from which we should be prepared to accept an order to kill. - Albert Einstein
