My $.02: PyPI consumers are not customers.  They are collaborators. 
They are collaborators who need to be paying active attention to what 
they're doing if they choose to install random stuff from PyPI.  Doubly 
so if they're automating that installation.  Triply so if the automated 
installation of a system must not break because they'll lose time or 
money or both as a result.

There is no sense in ever making an alpha release if it's never going to 
be installed by anybody.  I agree that preferring final releases should 
probably be the default for installer tools.  However, even if it's not, 
distribution creators shouldn't feel compelled to hold off pushing an 
alpha release to PyPI for fear that someone might actually use it.
