The reason I lean toward the direct launch model is that it gives the user a lot of flexibility in terms of using things like namespaces, DAC, cgroups, capabilities, etc. A lot of potential features are lost when you do indirect launch because you have to teach the daemon how to support each of these features.

But what's the alternative?  Teach the user how to do all these things?

You can expose layers of API. The lowest layer makes no changes to the security context. A higher (optional) layer could do dynamic labelling.

It's infinitely flexible, but it's not an API you can give to a management tool developer.

I think the goal of a management API should be to make common things very simple to do but not preclude doing even the most advanced things.
