pfDeleteFunc() registers such a function globally.

Per-class notification could be added without much
expense via a virtual function. Per-instance
notification would require an extra pointer (word) per
instantiated pfObject, which would be somewhat expensive
compared to its utility, at least if delete notification
were all it was used for.

A future version of Performer will have notification on a
per-instance basis available for destruction, as well as
other changes to an object.

Keep the RFEs coming. Now is a particularly good time to
bring up any limitations you've found, especially if
solutions might affect fundamental elements of Performer,
such as its memory, object, traversal or graphics
architecture.
