Re. resource limits, I meant more than just softlimit - cgroups CPU and network throttling.
Re. namespaces - sure, it doesn't have to be built in. But many people use it and it's convenient when it is.
I used the daemontools many years ago and remember fast cycling to be an issue which was worked around by manual pauses in run scripts. If it was fixed later - I'm glad it works.
But my main point was that daemontools worked great when we had simpler inits. Running it with inits which could restart makes sense. Running it with modern inits just doesn't give you anything interesting apart from another idle system process.
