I find Texinfo links to be a bit heavy, so I prefer not to put too many
of them, so the reader can concentrate on the subject.  Process filters
are not really relevant.

Fixed.

That's how Texinfo renders @emph in Info.

Sizewise, I fully agree, so I moved it to its own node/section.  I'm not
completely happy with the result, but I think it's better.

I'd rather keep the advice-add in the first node alongside the
add-function example, since as you say in many cases advice-add is what
the reader is really after.

I tried to clarify the notion of depth by spelling out what it means
for :after, :before and :override.

Of course it works.  The restriction is that the macro needs to be
advised before it is expanded.  I spelled it out now.
