I think Dave Baron's contribution to the HTML WG versioning issue
is in the genre you describe (unless by "neutral" you mean
"reviewed and endorsed by some group with mandate" in which case
I don't know of any such writing; opinions vary widely in this space)

He doesn't give much in the way of details about syntax; I think
the context of his message assumes that extensions will mostly
be element names, attribute names, and attribute values... oh...
and JavaScript properties and functions.

He recently updated/elaborated his thoughts in this space:

"There's been a debate in the HTML Working Group on distributed
extensibility; this led to a session at the Technical Plenary yesterday
(and, for me, an interesting lunch discussion afterwards that led me to
think about issues I hadn't before thought much about). ..."
