The only thing that pops up in my mind is that this should perhaps be
implemented using "resources" that we can "tag" using categories. The
idea with resources is that anyone can create a resource (owned by the
creating account, just like packages) and then attach it to a single
other SMObject (in this case an SMPackageRelease) not necessarily owned
by the resource owner.

And since an SMResource can have categories we can create a few
categories to "type" them OR we can have specific subclasses of
SMResource - like SMPatch or something that can also have an instance
variable referring to the "target" release or whatever.

So feel free to implement it! :)
