I tried that in Gnus (from the buffer displaying your message) and
I ended up in ~/.w3m - I get that not all buffers have files
associated with them, but perhaps this should be communicated
somehow instead of that kind of arbitrary (?) behaviour. ...

(After that.)

I don't really see how doing anything else would be better. It indeed
jumps to `default-directory', and that can be useful sometimes.

For example, as I'm writing this message, if I press `C-x C-j', Emacs
opens `~/News/drafts/drafts'. Which is relevant, at least.

And if you don't really want to see the directory it opens, just press
`q', the Dired buffer will be buried, and you will see the buffer you
were in before.

Yes, only, as was my case (in Gnus, `default-directory' wasn't set
so some other part of my Emacs activity - w3m, as it was - had
gotten there first, with no change) so the jump didn't make any
sense.

So, either a message could be fired off - file not associated with
file, using bam-bam-bam instead - *or* you could elaborate like
one line in the doc string on this.

I've now done the latter in Emacs 28.
