non-anonymous class

For some times, the gform_after_email started referencing (new Notifications)->delete_files instead of the former globally-scoped jbl_gfuaa_delete_files.

But this object is anonymous (in the sense of being stored in no globally accessible variable).
As such this hook not only can’t be removed, but can not even be *detected*.

I used to rely on has_action('gform_after_email', 'jbl_gfuaa_delete_files') and now have no alternative.

Could this be somehow changed?
Thank you.
