the concept of long IPC was abandoned by all modern L4-like microkernels
many years ago. The paper "From L3 to seL4 What Have We Learnt in 20
Years of L4 Microkernels?" [1] presents the line of thoughts behind this
decision.

Regarding inter-process communication on Genode, there is much more to
it than synchronous IPC. Please refer to Section 3.6. "Inter-component
communication" of the Genode Foundations book [2] to get a more complete
picture.
