 From what I understand, we are maintaining a whole set of components, 
developing a web UI, building a separate assembler module, adding and 
integrating a big third-party component (Keycloak), just to make it easy 
for someone to use "hawkular-core-services" in a particular way.

*This* is what is difficult for me to understand. I can't seem to accept 
that this 5 minutes test is a purpose, a "why".

In the end, what people will see after this 5 minutes test is not what 
Hawkular is.

All Hawkular releases so far had the purpose of being a monitoring 
platform. As a platform, our solution to the 5 minutes test was to add 
an embedded Cassandra and embedded Keycloak. That was our cost for the 5 
minute test. Everything else was supposed to be part of the product: 
multi tenancy, BTM, Data Mining, charts and so on.

To me, "hawkular-core-services" is essentially a data store. It is 
intended to be consumed by platforms "closer" to the end user, like 
OpenShift or MiQ. As such, I would expect as much of an UI to it as I 
would expect from, say, a PostgreSQL database server: I would certainly 
expect a way to manipulate and extract data, but I would *not* expect a 
full fledged user-friendly HTML5 snappy web UI.

If our raison d'Être is around core-services, then having this "bloated" 
distribution is doing a disfavor: it dilutes the focus we have, it 
prevents developers from using the time on our core business and 
confuses people who first got in contact with Hawkular.

More important than passing the 5 minute test is to clearly answer "what 
is this for and what can it do for me". And *this* is what I still don't 
understand.

Nobody said that.
