I disagree, because that depends on how you change the query. If
you're only altering one query_var, like say posts_per_page, then you
can still be on the front page with an altered query.

But if you only show posts from a category, then you're not on the
front page anymore, you're showing a category archive.

It isn't exceptional though. That's my point. It's just a way of
checking what's in the query. If you want to check if you're on the
root URL or not, then you shouldn't be looking at the query at all,
and you shouldn't be using is_front_page().

Basically, you're trying to redefine what is_front_page() does, in a
manner that is inconsistent with all of the other query check
functions, and I disagree with that. If you want to check the URL,
then write an entirely new function that does that. Don't change the
existing function to be inconsistent and different, because you'll
break expected behaviors.
