Not the parent, but I’ve had an issue where the fi ligature occupies just one character width, which looks very wrong with an otherwise monospace font. If the ligature is done right (resulting glyph is double-width), then I would probably like it.
Iosevka does not have `fi` ligature.
The "Term" variant is used for some restricted environments, like some Linux would think that Iosevka is not monospace due to it has glyphs wider than one space.
Good design choice. To be clear, my issue was with another font, not yours.
