If you don't care, why are we spending time on this?

All 3 of those groups are doing APIs.

Any group could specify an API that an implementer could apply to the
Element and Document interfaces for any language.  For example, the
Element Traversal specification, done by the WebApps WG, doesn't
explicitly limit itself to any particular markup; it can apply to any of
them.  Some parts of the HTML5 spec are being applied to SVG content with
no problem.  It's all one platform.  A modular spec needs to take 
multiple languages into account as a use case, but that's going to apply 
no matter where it happens.

It is about the presentation of the content.  You seem to associate the 
term "presentational" with a particular kind of markup (CSS presumably); 
I don't think that's a useful distinction, but I can simple say that it 
affects the presentation of the element, if that suits you better. 
(This is the same position Al McDonald has taken [1]).

The CSS WG is working on the CSS OM.  That's an API.

Yes, it could.

You keep saying that, but you haven't said why.

What are the criteria you are using for "the right place"?  An explicit 
answer to this would help us move forward.

Three people from Apple have suggested moving it to WebApps; I've also 
heard an offlist preference (before I started this thread) to that 
effect as well.

At least two people have publicly commented that they think this should 
be done in CSS, Alistair MacDonald [1] and João Eiras [2].  I've heard 
others suggest the same offlist.

What part of the W3C Process am I'm ignoring?  What is wrong with 
finding the right stakeholders... isn't that what we should be doing, to 
make sure it has adequate review?

Not necessarily.  That's why I sent this email (and come to that, I 
should probably send it separately to the SVG and CSS WGs).  If we are 
talking about concerns about patent commitments, that's a different 
conversation than where it "belongs".

I wouldn't expect Apple to have patent concerns about this, since you 
are suggesting moving it to the WebApps WG, where Apple is also a 
member, but if you do, your AC rep should contact the me or someone else 
from the W3C team.

Obviously, the same goes for any other member of these groups.

Again, that's the question I'm putting to these groups.

I don't see why it would slow down any other work here as opposed to 
some other group, such as WebApps.  In every group, it's usually a 
subset of the group that works on a particular spec.
