Fair enough. But can you provide some ideas of what non-combat functions that all fighters share? Because really, what defines a fighter is that they are good at fighting. Of all of the classes, they are the only one that really is defined by their combat ability.
For the most part, anything else I can think of might apply to some fighters, but not all. Certainly, within archetypes it's much easier to define. Knights have mounted combatant capabilities and leadership capabilities, for example. A strength-based fighter can be very athletic and carry more, but a dexterity-based fighter would be different.
For the base class itself, though, there aren't too many (if any) non-combat abilities that I can think of that should apply to all fighters.
So, I have three answers there.
First, subclasses (martial archetypes) are a *great* place to put varied non-combat abilities. There's nothing saying that ALL fighters need to have the same exploration/interaction features. In fact, if you look back at many of the AD&D2e kits, you'll see a repeating pattern of: The Cavalier receives a +3 reaction from anyone of his own culture (except criminals and characters of evil alignment, from whom he receives a –3). That's from The Complete Fighter's Handbook, and the cavalier kit wasn't alone – barbarian and berserkers definitely got that +3 bonus with different groups, and there probably are others I'm not remembering.
Second, as I previously pointed out in this thread, in old school D&D fighters had built-in non-combat identity as "Barons", ascending to political leadership, gaining followers, and earning tax revenue. A secondary identity as "the gear guy" was also built-in, with increased starting gold, percentile strength greatly increasing maximum load a fighter could carry without suffering encumbrance, and the only one who could use magic swords. That were part of the non-combat identity of ALL fighters and it was stripped away.
Third, I would assert that the fighter originated as a defender. And I'm not only referring to a tactical role. I'm also referring to the origin of a warrior class that was for the defense of a tribe or settlement. This assertion is reflected in the language used to describe the fighter class in the Rules Cyclopedia: In the D&D® game, fighters protect their weaker friends and allies. Compared to a ranger (who seeks out the horizon), a fighter can be seen as the one responsible for protecting the hearth – earlier I gave some examples of camp talents that I'm playing around with in my own fighter redesign.
