The efficiency problem becomes obvious when you consider a user who accesses a website site many times. For example, imagine using an anonymous credential to replace Google’s session cookies. For most users, this require obtaining and delivering thousands of single-use credentials every single day. You might mitigate this problem by using credentials only for the first registration to a website, after which you can trade your credential for a pseudonym (such as a random username or a normal session cookie) for later accesses. But the downside of this is that all of your subsequent site accesses would be linkable, which is a bit of a privacy tradeoff.

You might wonder why not just put everything that is “infrastructure related” in a dedicated directory inside the Business-Module. That’s the approach often taken in many designs in the wild, but the problem with such a weak separation is that it tends to erode (and after many months you discover that a business class peeks messages in a broker). Another problem is that it’s much harder to find the boundary for unit tests (whereas with BM and IM separated, you can just assume that the public API of BM is what should be unit tested).
Tens of millions of people already use European or open alternatives across these categories. The challenge is not proving they work. It is getting from tens of millions to hundreds of millions.
