Hi Rafeal,

Apologies for the delay. I understand that turning internal details into an
ABI can severely hinder future improvements, and I acknowledge that this is
a critical barrier for the current approach. I do not currently have a more
specific or compelling use case beyond this initial need.

Please ignore this patch.
