DejaVu needs a semi-bold weight to accomodate people who feel regular is too
thin and people who think bold is too heavy compared to regular
Please make sure that the extra font weights (extra light, semi bold, etc.) map
to the 9 steps of boldness defined in CSS.
We currently have:
200 - ExtraLight
400 - Book
700 - Bold
This leaves rooms for 100 (Thin*), 300 (Light), 500 (Medium), 600 (SemiBold),
800 (Black), 900 (ExtraBlack).
* Names should not matter, systems that use them in the backend are flawed.

With their WeightRat = CapH / WStem(E) we have:
ExtraLight: 14.6 (10 <= WeightRat < 18) -> 300 (Thin)
Regular: 7.4 (5.5 <= WeightRat < 7.5) -> 500 (Medium), 0.1 short of being 400
Bold: 3.9 (3.5 <= WeightRat < 4.5) -> 700 (Bold)
Legacy systems would need families of 4 styles. We recently split ExtraLight
into another legacy family: DejaVu Sans Light. Here's a list of what the
families could be:
Thin : 100
Light : 200, 300
Regular : 400, 700 - Current default family
Medium : 500, 600 - strange family in between Regular and Bold
Black : 800, (900*)
Anyway, it will take time before anybody seriously starts working on these.
