It seems to me that all of these solutions focus on making mash do more 
stuff, without ever changing Koji.

But couldn't the Koji API grow a new parameter, which would be used for 
specifying how many versions of each package to get at most?

The current behaviour would be obtained by setting it to 1, and setting 
it to 2 would already be a positive change as it would allow downgrading 
a package if the update went wrong.
