It's not gnomes that go in for turtle-hats. It's were-rabbits.
In 3.5/Pathfinder each of these had different strengths and weaknesses and emphasize different styles of play. The long sword was the most common sword in the game because it was a good basic weapon. The bastard sword did more damage but required a feat to use it one handed. Few people used it for that reason. But I imagine that those that did use it remember that character well. They dealt out more damage than their long sword counterparts at the cost of a feat. So a fighter with feats to spare would find something like that useful. A great sword delivered even more damage but at the cost of a shield. This would work well for someone that cared more about offense than defense. Meanwhile the rapier dealt the lowest amount of damage, but had a higher crit range and worked with the Weapon Finesse feat. So you could make a fast-footed character and if you took the Improved Critical feat with it, you were threatening a critical attack once every four hits. That is pretty darn powerful. And none of that would be serious choices if they were all lumped together into "sword."
At this point in my life, I am far happier with an equipment list that says "sword" over an equipment list that has 5 pages of swords with a million different subtle effects, spread across a dozen different books.
I don't want people wearing turtles on their heads because it gives them a +2 bonus to diplomacy with gnomes, and they'll swap it out for a duck on their heads with elves (+2), wear sponges on their feet (+1 sneak), etc.
I want someone to wear a turtle on their head because it's a choice they've made about their character to make the character more interesting. Done.

This, this, and this again. All this. 100% this.
The point I was trying to make is that if you make a one size fits all "sword," some people that would take a dex-based rapier are not going to go with "sword." They will make a strike from the shadows dagger wielder, who is different from a dashing swashbuckler fencing rapier wielder. Why, because mechanically, that will work better than being penalized for making a quick character that can't use dex to hit because "sword" doesn't allow that option.
