It's true that LDView wouldn't be able to create substitutions at its lowest primitive setting of 8, and having the tang primitives work with an 8-sided primitive would be nice, but it doesn't seem like something that can be done now. I'll investigate supporting this primitive. It doesn't appear to be very difficult (although supporting it in POV export where it's most useful may or may not be hard).
As you say, we could live with this (currently we already have the 1-16chrd and the 4-4ering primitives that don't play well with odd primitive substitution notches). Or we could obsoletize current tang primitives (used by very few parts anyway, only two AFAIK).
