That wasn't my intention when quoting the old documenting guide, it was just
to show what the intent was (and still is), and that I didn't just invent it.
As Fred says, the status quo is not sacred, but we are usually pragmatic and
a nontrivial amount of weight is needed to change it.

It's one interpretation, yes. My interpretation (which coincides with the one
written back then by Fred) is that the versionchanged applies to the API item
in whose block it occurs. And a function is not *added* by the addition of
a parameter, it is *changed* by that. The parameter itself is not a marked-
up API item. If the structure was like
.. function:: foo(a, b)
.. parameter:: a
.. parameter:: b
then adding a parameter c would definitely be marked up as
.. parameter:: c
.. versionadded: 3.x
Anyway. You think your interpretation is better, others including myself
prefer the current one. This is exactly the kind of argument where the
status quo wins because the churn necessary to change is not justified.

Again, you're mistaking the reason I quoted them.

That's a nice strawman -- we all feel semantic markup is important, and we
are talking about nothing but semantic markup here. We're just discussing
the interpretation of one aspect of the semantics.
