When will Glottal Effect come back?

When will Glottal Effect come back? It may have some problems but it’s really a practical parameter for creating some special effects. Can it be released earlier? (some problems can be solved later while updating QwQ)

I liked to use it in combination with cranking the breath all the way up and it would create a realistic whisper, it did have some issues with it being very hard to emulate an actual growl or scream, but it did make a great whisper effect with one of the settings.
I used it like that in this song
