Yes, almost surely..

The problem with current ESS-core  ... or with Emacs 23 ... is that
none in ESS core is saying he could try to do the work
finding the parts of the current code that only work with emacs 24 and
either replace them with e32-compatible versions / workarounds,
or isolate those parts (to not be loaded) if they are not essential for ESS....
a combination of what we had always done in the past,  much of it,
nudged at least, by myself.

My conclusion is : You declare  ess >= 16.04 as  "emacs 24"-only.

We (ess core) must do the same:  Our current documentation in this
sense is wrong as it claims ESS would work with emacs 23.
