Glad to hear that!

Pipelines (together with the rest of the akka.io package) were experimental in 
2.2.x, which is quite similar to deprecated in a way already: instead of 
knowing that it will go away, you know that it may change or go away. As I 
said, it would have felt dishonest to keep pipelines in the published artifacts 
while knowing that people struggle to get them to work only to discover one 
release later that they need to figure out something new.

We know that people have been running their business on a 1.0 milestone of 
Akka, or used the experimental Cluster successfully, and this has maybe led to 
the expectation that even our experiments are highly reliable—which we feel 
honored by—but the truth is that in fact some things do not turn out well 
enough after all.

Regards,

Roland
