Since floats and less-than-5-term vectors are automatically promoted to
5-term vectors this is not necessary. To the contrary, what you suggest
might be misinterpreted to imply that e.g. `rgbft <4_Term_Vector>` would
be invalid, when in fact it is perfectly legal.

Also, there is no `rg0` keyword, so that's plain nonsense right there.
