Nobody bothers with that any more.

I presume that's meant to be hyperbole. Plenty of C programmers do
bother with that.

Most seem to assume that () already
means zero parameters anyway, judging by the incorrect usage I
constantly saw in open source code.

I find it better to write correct code than to look for excuses
to write poor code. If I define a parameterless function F, I
absolutely want a diagnostic if I call it with one or more arguments.
If nothing else, it's an opportunity to set a good example.

The declaration "int F();" is correct code. Just because you
don't like it doesn't mean it's wrong.

You're right. I see that I unintentionally implied that it's wrong.
I should have written "good code" rather than "correct code".

"int F()" is correct code. For pre-C23 versions of C, it is in my
opinion inferior to "int F(void)".

I'm aware that you think "int F()" has some advantages in some
circumstances.
