Whenever I see a new interesting terminal emulator my main prerequisite to see if it's worth playing with is if it supports bitmap fonts, and unfortunately this one fails the test. I can't live without bitmap monospace fonts. I don't have a fancy 4k monitor so TTF fonts are blurry in comparison to a crisp bitmap font.
Your thread at https://news.ycombinator.com/item?id=45354014 can probably be extended from that particular one to all terminal emulators that have "We use the GPU!" on the marketing features list, because they are all influenced by alacritty and Goyal's Kitty.
Those two are already balanced by Zutty and Rio. So let's have a look around at some of the emulators that make using the GPU a marketing point.
DarkTile (https://github.com/liamg/darktile) accepts TTF and OTF, so presumably if you can get your bitmap font of choice converted into those formats you are alright.
GhosTTY (https://github.com/ghostty-org/ghostty) gained proper bitmap font support just last month, the issues list says, but is reliant upon what FreeType and CoreText can handle. It has an open issue discussing those vis-a-vis bitmap fonts.
