Except in games that don't allow the optional component of feats.
Not to mention that feats really don't even give the fighter much of an edge. The most commonly touted feats for non-combat capabilities are Actor, Observant, and Skilled.
Actor gives you advantage on Persuasion and Deception, but only when you are attempting to impersonate someone else. I don't know about you, but most Persuasion and Deception checks I make aren't when I'm pretending to be somebody else. Besides, to really make good use of this feat you need a good charisma score or expertise in those skills. The fighter will usually have neither. Generally, even with this feat, the party warlock, paladin, or sorcerer will have a better chance to impersonate others than the 12 Cha fighter.
Observant suffers a similar problem to actor. Their are other party members who will typically be better at being "observant" than a fighter who takes this feat.
Skilled is great, but it is giving you your 5th, 6th, and 7th favorite skills as your number 1 to 4 choice is probably already taken by your free class skills and background. And again, you won't ever be better than someone in your party with the appropriate primary attribute and proficiency (or expertise).
Those feats definitely give you some breadth, but they don't allow you to actually be better than most of your party members who didn't even need to devote resources to their non combat utility. What is worse, those feats cannot hope to match most other classes non combat features.
Take a level 10 fighter for example. He has 1 more feat than everyone but a rogue. Is a feat as good as a bards Jack of all trades, inspiration, expertise and spells? Is 1 more feat as good as a Rangers spells and favored enemy/terrain? Is 1 more feat as good as a Paladins immunity to fear, aura thy protects allies, 50 HP lay on hands, divine sense, and spells? Is 1 more feat as good as warlock invocations like at-will Jump, levitate, or disguise self? Those classes can all do about as much, or more damage than the fighter, but also gain tons of utility. I'm really not seeing how Actor, Observant, or Skilled can come close to matching the non combat potential of most of those abilities.
