c:maj inconsistency

[Graham Percival]

Exerpt from Chords:
---
maj
    The major 7th chord. This modifier adds a raised 7th step. The
7 following maj is optional. Do NOT use this modifier to create a
major triad.
---

In other words,
  \chordmode{ c:maj c:maj7 }
produce the same chord, although
  \chordmode{ c:m c:m7 }
don't.

Why?  IMO, it would be much clearer if 
  \chordmode{ c c:maj }
produced the same output.


No, I'm not offering to make this change myself; I'm just seeking
arguments against adding this as a feature request.

Cheers,
