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
