Edit: title updated. See comment #3. Upon upgrading to 2.27.1, I find that snapcraft no longer builds my trivial test snap (hosted here: https://code.launchpad.net/~thomir/+git/thomir-says). It looks like the executable script is no longer being staged, but it does appear in the 'build' directory. While I don't mind that my test snap no longer builds, I worry that this may represent a major regression for all (or at least some) python-based snaps.
