Thank you. Some comments follow.

I don't think we should do that. It is up to the user to install
ShellCheck if they want.

For example, installing `emacs-flycheck-haskell' doesn't pull GHC in
user's profile.

Nitpick: you can remove the (emacs-26+) part.

Nitpick: since you seem to talk about the tool as a whole, I suggest:

  @command{shellcheck} -> ShellCheck

I think you can remove the last sentence.

Could you send an updated patch?

[bug#41731] [PATCH] gnu: Add emacs-flymake-shellcheck.

[Fredrik Salomonsson via web]

Thanks for the feedback.
I was debating to myself whether to include shellcheck or not. As when I looked around in emacs-xyz.scm, for example `emacs-ag' does propagate the-silver-searcher but `emacs-direnv' does not.

Anyway, I removed it in the latest patch.

emacs-ag package contains a comment explaining why the propagated inputs
is required.

Sometimes, it is unavoidable, but usage of propagated-inputs should be
as limited as possible.

Thank you. I applied your patch.

Sorry, sent the old patch again. The last one should be the correct one.
