On many systems this default would mean Python 2. Even if the official
recommendation changes for 3.5, the status quo might linger for a few
years.
On the other hand, the number of distros that don't ship Python 3 is
small, and the reason they're slow-moving tends to be stability and/or
compliance, so they're not the target audience for zipapp. And the
python3 symlink is not going away any time soon.
So I'd suggest `/usr/bin/env python3` for the default.
