groups are a syntactic shortcut who's initial purpose was to simplify  
migration from v1 configs.

the tradeoff for not having to specify the constraints is that you  
only get access to a limited set of v2's capabilities^ (one that cover  
the most common use cases).
reload is not one of those capabilities.

if you need access to the full power of v2's resource model, don't use  
groups.


^ the alternative being I'd have to programatically support every  
potential combination of constraint and resource options within a  
group - which isn't going to happen.
