Still supported, but deprecated. There is a way to re-enabled it, but it 
not performed by default.

The "block communication" is fully supported in 3.0.0-beta-1-SNAPSHOT 
but not enabled via the "blockcontext:/" protocol.
This is the reason why I have published my sample project [1], e.g. to 
show how to achieve block communication *without* blockcontext:

As you have requested in another e-mail of this thread, I will also 
update [1] with another block's pipeline invocation. I'll keep you updated.

Consider that there is still the possibility to use blockcontext: 
protocol in 3.0.0-beta-1-SNAPSHOT, even though you will need to make 
some modifications on the project generated via archetype. I will add 
this to the page for COCOON3-119 [3].

FYI, You can read through COCOON3-105 if you want to understand more the 
reasons behind this switch.

Regards.
