release by subsystem

    I am curious if you envision to change karaf layout so release by
    subsystem is possible.

    For example, if I use minimal sub set of karaf, which does not need
    Aries, why should I wait for it?

    this is similar to how ops4j was partitioned way back, so there are
    no monolithic Godzilla releases any more. 

    Thank you,

    Andrei
