In what way is the SYNTAX different? We seem to agree on this:

First and foremost, in <dl> the order is all important. Here it would 
not matter.

In <dl> one may have several <dd> for each <dt> (or several <dt>'s in a 
row), here one may not.

You call this "minor", I say confusing. But we have in fact created a 
new syntax - why is that better than creating new elements?

In what way is the SEMANTICS different?

Well, that is not what the SPEC says is it?

Yes, I would.

I am arguing in favor of introducing a new element, which would be the 
zero cost solution, since <details> is new anyway.

+ No hacks besides those that we already use to get details working as 
such in legacy browsers.

+ When implementing details the browser vendors will not have a harder 
time using a new element than they would using dt/dd.

+ We would keep the several meanings per element count down, which from 
a teachability POV is more important than keeping the total number of 
elements down.

And from that POV nuances are often harder to pick up than anything else.
