>jaggies are a visual distraction
So are serifs, and people don't complain about those. Whether any "visual distraction" actually distracts you is a matter of what you're accustomed to. If you read enough cursive or blackletter it will start to look normal to you. I disable anti-aliasing because I'm accustomed to aliasing and it doesn't distract me at all. In exchange, I get sharp text on an 1080p monitor, effectively quadrupling my graphics performance because I no longer need 4K. I'd prefer bitmap fonts, but in practice I find full automatic hinting of vector fonts good enough.
The only cases where I can see anti-aliasing helping are with Chinese and Japanese fonts, which have characters with unusually fine details. But on any GUI using Fontconfig you can enable anti-aliasing for those fonts specifically and leave it disabled for the rest.
Serifs are chosen intentionally to be harmonious with the overall letterforms. They provide a feeling of visual stability and additional cues for recognizing letterforms. They provide a kind of consistency. They're not a distraction.
Jaggies come from a limitation of the pixel grid. They arbitrarily make diagonal strokes and curves bumpy while horizontal and vertical strokes are perfectly smooth, an inconsistency that would otherwise have no rhyme or reason behind it. Before letterforms were constrained to square grids, nobody was making diagonals and curves bumpy because it was a desirable aesthetic effect.
Jaggies are a distraction from the underlying letterform we all recognize. We know they are an undesirable distortion. Serifs are not. They serve an intentional aesthetic purpose, proportioned in a carefully balanced way.
Serifs are a skeuomorphic artifact of stone-carved text. They're no more legible than sans-serif fonts (see https://news.ycombinator.com/item?id=47492894 ). The only reason people like them is because they're used to them. You can get the same feeling from bitmap fonts if you read them enough.
I very intentionally didn't say serifs were more legible than sans-serif.
There are reasons people like them more than just that "they're used to them", however. I named a couple of them. Just because they originated in stone doesn't mean we kept using them for the same reason. A lot of things originate for one reason and then become used for other reasons.
Believe me, I got "used to" bitmap fonts throughout the 80's and 90's. But I still always preferred the 300dpi version of a document from my LaserWriter and then inkjet. Getting used to bitmap fonts never meant preferring them for general computer usage. Jaggies that appear arbitrarily on some strokes but not others is not visually pleasing. Nostalgic, maybe, but virtually never anything you'd choose if you weren't intentionally trying to create a retro vibe.
