Shen did a fantastic job helping out this open source project.

That goes without saying. It was broken.
But what of the future?
You have no cryptographer since Tecnovert left.

Is ShadowSend now fully peer-reviewed and secure post-Shen? Or could there be other exploits?
How will you regain trust?
If Monero had been deanonymized the way ShadowCash has been it never would have recovered.
