As pointed out by Suvayu Ali, you can define a new "overprint"
environment, but it won't provide the "\onslide<...>" macros. You'll
have to rely on "#+beamer: \onslide<...>" keywords.

In general, you close a headline with another headline (i.e. a block in
Beamer jargon). You can also close a block with an "ignoreheading"
headline. That's how columns work.

Here is an example:

#+begin_src org
#+BIND: org-beamer-environments-extra (("overprint" "O" "\\begin{overprint}%o" "\\end{overprint}"))
#+LANGUAGE: en
#+OPTIONS: H:1 ':t

* The Things

** Things

   #+attr_beamer: :overlay +-
   - foo :: the first thing I want to talk about
   - bar :: this is the second, follows the first
   - baz :: third and final

** Overprint
   :PROPERTIES:
   :beamer_env: overprint
   :END:

   #+beamer: \onslide<1>
*** Foo

    A picture of a "foo".

*** onslide                                                      :B_ignoreheading:
    :PROPERTIES:
    :BEAMER_env: ignoreheading
    :END:

    #+beamer: \onslide<2>

*** Bar

    Some text about "bar".

*** onslide                                                      :B_ignoreheading:
    :PROPERTIES:
    :BEAMER_env: ignoreheading
    :END:

    #+beamer: \onslide<3>

*** Baz

    Content relevant only to "baz".
#+end_src
