I actually agree and want to increase my main body font size. It’s also probably time to go serif, as sans-serifs are best suited for low resolutions (like for body text on all computers and mobile phones up to ~8 years ago) and serifs shine in high resolution (like on the printed page); today high-density screens are more common. Even “1x” monitors are wide enough that the increased font size they make possible increases the number of pixels available per rendered character. In the mean time, browser zoom will work well!
