Yes, indeed.

If the name has a common meaning, it is obviously not useful to abuse the
name for something different. The opposite case has an advantage.
For example in physics or mathematics often words are taken and 
specified in more detail, what they mean, but they are not taken to
specify something completely different to confuse the audience ;o)
I think, 'interactive content' has not a very specific meaning in 
general, only some associations for example with the related 
behaviour in SVG with interactive begin and end of declarative
animations etc.

Well, if there is no better, then an author has just the choice between
another language or to use an element with a related meaning and
sufficient structure - I do not think, this is good at all, it only shows, 
that the language in use is still rudimental.

Why it is, is already detailled in the wiki:
Some specific elements would be better, but before they 
exist, this fits best...

There is not reason to repeat the arguments in any email again...

Sure, several of them have similar problems, that can be covered
sometimes approximately with dl/dt/dd or some other elements and
some crutches in HTML4 or XHTML1.x, if the meaning and usage of 
such elements is not restricted by the specification.

Because the values of class have no predefined meaning, this is a
crutch too with its own problems. In combination with CSS it helps
to align the presentation to something useful, not the markup of
the content at all.
Obviously this could be covered with attributes like role or kind
with predefined meanings in HTML5, if this is done and the usage
of realated elements are not restricted to exclude such usages,
this would be sufficient - just do it ;o)
