Not everybody agrees on the best way to draw text (some people like it blurry, others like it higher contrast), so I think the target users may matter to some level. It also varies by OS, and the OS even have options to let users influence it in some way.
Have you also noticed how even color rendering varies by browser? This is less intuitive...
Seeing the font feature reminded me of a recent web design I did that loaded a custom local font. Anyone know why Webkit and Blink browsers differ so much with local font rendering? Matching designs was a nightmare in all major browsers and OSs, and that genuinely surprised me for frontend development in 2018. Why are major browsers differing on this still?
