It’s what everyone used back in the Quake 3 days.

Fun fact: 0ad still doesn't support kerning. While I would've loved to see proper kerning support in r28, there is only so much a team of volunteers can do.

If you're interested in progress in this area, I suggest you keep an eye on https://gitea.wildfiregames.com/0ad/0ad/issues/7945

This is an odd comment on a website where most users are happy working with mono-spaced text most days. Not everyone has kemingphobia.
