It happens quite frequently. Here is an example without controlled 
objects, just an illustration of a dynamically selected storage pool.

Consider a JSON parser. It is be an Ada object with a buffer inside 
which size is a discriminant. On top of the buffer sits an arena pool. 
The parts of the parsed JSON object are allocated in the arena. After 
parsing the result can be used until the next parsing that will sweep 
the arena, no Unchecked_Deallocate.

In this case the collection rule will have no effect since JSON objects 
do not require controlled components (or tasks, yet another thing killed 
by the collection).
