Mind you, eventually this will be correct... just it's been declared prematurely for 60 years and so this still may not be the correct moment to say so.

Missile performance won't be equal in this case; if the enemy can launch missiles with higher pkill, well..
The enemy COULD pop out from just behind the mountain/hill in front of you, and force you to have to resort to short ranged (FOX 2) missiles or even guns.
Still, though, this is not enough to prioritize extreme agility over stealth today. The F35 is more than agile enough for the few times this occurs, especially if there is a wingman around.
My understanding is that the "dogfighting is over" rhetoric stopped being proven wrong during the Iran-Iraq war, when Iraqi fighters started mysteriously exploding in the sky during operations.
If you can safely entirely rely upon on IFF and deconfliction, all is great.
If you ever have to close to identify targets, then you might end up with some significant maneuvering, etc. Of course, the F-35 isn't terrible at this, and stealth and efficiency lets it better choose the terms of this engagement.
