There are other uses I see for this API:

- It can be used to register release functions to be called at shutdown time,

- It can be used as a "cleanup stack" [1],

At any rate, what I don't like about the proposed API is that the reversible
is implicit.  That would be cause for endless confusion.  I'd rather see
reversible objects being passed around like GError and GCancelable.  Perhaps
GCancelable can be reused indeed.  You can just add a method to GCancelable
that adds a "release" function to be called if the cancelable is ever canceled.
