That's a good point.

Probably not many packages are likely to provide pypy{,3} invoking binaries
(ipython is probably actually a good candidate here) and so it probably
counts as an exceptional case which can reasonably bypass a recommendation.

I suppose you could:

 * Not ship any executables which invoke pypy. For pypy3, that appears
   to be the case today (nothing in /usr/bin using pypy3 except the
   interpreter itself).
 * Ship the library and python3 executable together (possibly with a
   Provides: for the executable), and the pypy3 executable in a
   separate package (since the library itself presumably
   doesn't want to depend on pypy3, and might need to depend on
   pypy-specific library packages). This saves 1 binary package but
   seems inconsistent. The actual implementation could be picked with
   update-alternatives.
 * Ship library, python3 executable and pypy3 executable separately.
   This seems more consistent but generates an extra binary package.

This is probably a good case to consider in this thread because ipython
and ipykernel are probably reasonable cases where a pypy-specialised
executable might make sense, and ipython at least depends only on
pure-python modules which work out-of-the-box with pypy.
