If these are useful for something then, yes, they should be wrapped. I
wouldn't bother creating extra directories for them, but you might want
to use doxygen groups in the documentation to group them together. For
instance, see the TreeView group in gtkmm.

But I wouldn't bother wrapping any of this until you have discovered
what an application might want to use it for, and can think of an
appropriate small example in C++.

I guess these are just standard plugins. Milosz is working on a way to
get access to specific API of elements (provided by plugins, I believe)
that are discovered at runtime (or expected to be discovered at
runtime). It's a code-generation tool for use by applications, I think,
roughly equivalent to how users of CORBA or COM generate code to use
APIs.

Again, this seems to be plugins.
