That's fixed, thanks to a community contribution! [1] For what it's worth, Typst did have font subsetting from the start, but it was rather bad for CFF-flavoured OpenType fonts.
The same contributor has recently put a lot work into building a better foundation for Typst's PDF export [1], which decreases file sizes further, and brings many further benefits.
