Looks good in general.

Why would one ever want a language other than the current one?
But it'll be nice for debugging purposes at least.

Good.  Very useful.

Aren't you confusing two things here?

1) Citation mode (numerical, author-year, author-number, in footnotes,
   in text, ...);

2) Citation type (in parentheses, within text cited as person, within
   text cited as title, ...).

I don't think it makes much sense to change the former locally,
whereas the latter should be specified each time.

At least it's easy to understand, and I cannot think of anything
better.

We probably want more than one field for this.  For instance, Natbib
allows the following:

  \citep[see][chap. 2]{key} =3D=3D>> (see Jones et al., 1990, chap. 2)

BTW, Natbib also allows access to individual parts of an entry:

  \citeauthor{key}     =3D=3D>> Jones et al.
  \citeauthor*{key}    =3D=3D>> Jones, Baker, and Williams
  \citeyear{key}       =3D=3D>> 1990
  \citeyearpar{key}    =3D=3D>> (1990)

I think we could generalise this a bit to allow access to any part of
the entry (e.g., title, short title, pages, ...).

What do you mean by this?

I must admit I think it's dangerous to have only one general command.
I think it was wise that Natbib split \cite up into \citet and \citep
to make authors conscious about the difference.
