I do understand your feelings. The problem is there were already many
points raised both pro and contra adopting Salt as an agent. And so far no
consensus was reached on that matter. Maybe someone else is willing to step
out and write a PoC for Salt-based agent? Then we can agree on a
functionality PoC should implement and compare the implementations. The
PoCs also can reveal limitations we currently don't see.
