"Desperately trying to run away" sounds a bit too "strong" (bah, can't
find a word for it).
It's just that we had something like:
for example. (Well, this is an example of something you mention below,
as a candidate for elements, not attributes, but still...).
Don't get me wrong, I don't find using attributes bad or anything.

Yes, these are the good guidelines we should use.
But still, there is also an important thing about making the profiles as
much _readable_ as we can. IMHO, that's a very important thing, and
sometimes, attributes can make that "look and feel" a bit ugly and
profiles hard to read.
But I agree we could use them a bit more where they clearly belong, as
you're stating above.

Command-line parameters probably don't belong in attributes - I think
they are the part of that "more items" category you mention.
But the others could. However, if we start using all of them as
attributes, the start tags of some elements could become quite a mess?

This is in my (personal) TODO for a long time (well, since you
mentioned it for the first time). I have put it on top now. :)

Yes, more examples of different structures would be useful.
