 probably too unique to be shared. But it should expose an API that can be
 used in these screens, so as to spare oneself the hassle of needing to
 rewrite the workflow-related functions for each of plugin, theme, core...
 and in my case, skins.

 I dont think abstracting this is going to be possible (or rather, A good
 idea)

 Different API's return different results; Different input sets require
 checking different fields; Different Expire methods; etc. In the end, An
 abstracted method is going to take up more code, and not gain any benefits
 over something similar to whats in {{{wp-includes/update.php}}}

 Much like the UI cant be too generic, Nor can the update checking..
