My experience was it never came up ... certainly had the potential to show a fighter as awesome but in practice not really.
Thing was, by the time it started to really matter, the monsters in question had stopped mattering...
...or stopped fighting you directly, per Tucker's Kobolds.
. I kind of think the best ability that could be given would be something along the lines of leadership and kingdom building. I may be nostalgic for those days of ruling domains.
What'd that actually do, though?
I mean, in 1e it was prettymuch a money pit and followers that couldn't much help you. In 3e, the Leadership feat gave you a reasonably useful cohort. In 4e you could gain "leader" abilities as a warlord, and there were Paragon Paths and even the likes of a Legendary Monarch epic destiny, but the focus of the game was adventuring, not running a feudal kingdom.
5e doesn't have much going on along those lines, either.
Hmmm I suppose one could give fighters better ability to use magic items in some way if you are trying trying to hearken to the past.
Always fun to hearken.
5e doesn't 'assume' magic items, though, so like oh-feats'll-fix-it, not really a clear solution.
