What does it mean for a font (or typeface) to be "quasi‑proportional"?

Also, whoever said that fonts intended for a terminal need to be narrower? Some terminals have narrower chars, some wider. And terminal emulators often allow for multiple char aspect ratios - e.g. via bitmap fonts of different aspect ratio.

Anyway, the typeface looks interesting, but I would have liked for the creators to compare and contrast it with existing (and popular) monospace / terminal-oriented typefaces.
