Typically, if word name ends with a question mark, the first (top) output parameter of the word is a *flag*. And it's true for all standard words. (though, opposite is not true)

But these words do not return a flag in the first output parameter. So, their names violate the common convention.

Sure. But the mentioned conventions seem good.
 
If you are proposing generally useful words, and their names violate a common convention, you could probably explain why it is not worth following that convention in this case (or in general).

Convention means doing something in a consistent way unless there's a reason to do
otherwise.  The standard had no qualms defining the word ? which leaves no flag.
I don't feel any less entitled coming up with names that are short and to the point.
