Do I understand you right?
You prefer a Chest, which is _not_ able to solve such a deep mate at all
(of course this is impossible with brute-force!), instead of a Chest with
an _additional_ mate solving mode, which _can_ find such solutions
(although it´s not guaranteed to be the shortest one)?

If this is the common opinion here, I see absolutely no reason to make
this new Chest version (with my enhancements) available to the public! :-(
