If the goal is to increase transparency and honesty, why would one hold it back? Just curious.
It's not like people are going to automatically jump at a new company that first introduces the method.
That's a great question. This is a common issue among crypto-developers. You may have heard the mantra from developers, "Write it, even if it breaks." Unfortunately, crypto-developers aren't afforded the luxury. If crypto is implemented and breaks, it can cause direct harm. Total losses, breached accounts, really bad stuff. Look at Meteor. They had SRP implemented but reverted back to bcrypt because maintaining the crypto code required far more resources that were best used elsewhere.
In a nutshell, I had penned an implementation a couple of years ago, had it in peer review but it quickly became cost prohibitive.
Granted, I can't speak for an organization that is interested in the research. It may end up being a benefit to all. Some time and resources to fully publish, maintain, and be there to actively improve the work.
