I like :wrap. What's more, remembering that old thread where
some questions about code before/after the image were discussed,
what if the expected value of :wrap were a kind of template? This would
allow code to be placed before and/or after (not just an environment)
the image, always within the float environment, if it exists. Something
like this:
#+ATTR_LaTeX: :float nil :wrap
\begin{minipage}[b]{10pc}\small\n%s\n\end{minipage}
#+CAPTION: caption
[[file:foo.png]]
Thus :caption with value nil does not add any higher float environment
and would enclose (always within the template) the value of #+CAPTION as
\captionof{figure}{caption}. Of course, with a float environment
declared, :wrap can still be used. An internal environment is unlikely
(I can't think of any use case right now), but you can add arbitrary
code like \captionsetup{} or \ContinuedFloat, which should always go
inside the float environment.
The result of the previous example could also be obtained with:
#+ATTR_LaTeX: :float minipage :placement [b]{10pc} :caption
\captionof{figure}{caption}
[[file:foo.png]]
I don't know if it would be appropriate to explain in the Manual that
doing so would not be... "correct"? I don't know if there is any term in
programming to designate these situations which, without being bugs, are
functionalities not consciously sought...

I like the idea, but unfortunately, apart from the known float
environments, there are those that a user can define using the \newfloat
command from the float package.
