ok, I will look into all this tonight.

(because the spec doesn't have a non-parallel version).

I was merely checking that every required dependency was also available and to my surprise
the temporal service was marked unavailable until the CM had completed what it was doing.
> 1) Shouldn't temporal service be always available externally via available property and
keep track on the actual state only internally? This approach might not be backwards compatible.
> 2) Could temporal service be allowed to be marked as optional. This would suit my use
case, but it feels like a 'golden hammer' approach because it alters component's state machine
behavior a bit which in turn can be harmful for other use cases. 
> As a workaround I'd have to differentiate the dependencies somehow from each other, but
I see that the 4.x has removed the dedicated interface that I was thinking of relying upon
