    I find several things wrong about the concept:

    The first thing is that it is not clear: it changes continuously
from accelerating init to encompassing the wole OS.

    The initial goal it was advertised for, accelerating init, is
futile since the init speed is mostly driven by the speed of mass
storage access, and, in addition, for servers, is negligible compared to
BIOS startup and tesing time.

    It ends up with replacing all Unix/GNU/Linux commands by systemd
commands, and, this way substitutes a new API between the OS and the
user: you buy Linux-GNU and you get Systemd.

    It makes everything more complex for actually no gain. But even if
there was a gain, the cost is too high.

    YES! I fully agree with you on this point; this is the question I
would like to get the answer to.
